Best Sbc Head Bolts For Aluminum Heads: 9 Kits Compared

#1 · Best Overall

1. ARP 134-3601 Hex Kit

• Thread Size: 0.65 inch
• Fastener Size: M16

Best for: Stock-size SBC hex-bolt buyers.

Why it ranks #1: Listed as an SB Chevy cylinder-head bolt kit with part number 134-3601, it offers the clearest direct SBC application among these listings.

A stock-size, hex-head configuration gives the ARP 134-3601 a straightforward direction for Small Block Chevy builds using this fastener style. The listing identifies it as an SB Chevy head-bolt kit, with a vehicle-specific fit type, so buyers can focus their compatibility checks on their particular engine and head combination.

The hex head provides a familiar wrenching format for installation, while the stock size designation points buyers toward a standard-size application rather than an explicitly oversized fastener. ARP identifies the kit for Small Block Chevy use and lists a 0.65-inch thread size and M16 fastener size, making those specifications useful checkpoints when matching the bolts to an engine. The listing also gives a vehicle-specific fit type, so verify the exact application before assembly.

Skip it if you need a kit expressly identified for aluminum-head use; ARP 134-3703 lists retorquing-friendly flanged heads and hardened washers.

This suits a Small Block Chevy owner seeking a stock-size hex-head kit and willing to verify engine-specific compatibility. Its listing does not establish aluminum-head suitability, so make the head and fastener match a priority before choosing.

#2 · Specified Strength

2. ARP 134-3703 High Performance Bolts

• Material: Stainless Steel
• Thread Size: M10x1.25 or 3/8''-16 UNC
• Fastener Size: M10x1.25 or 3/8''-16 UNC

Best for: Retorquing-access priority builders.

Why it ranks #2: The listing specifies 180,000-psi bolts, 12-point heads, and hardened parallel-ground washers, though it does not state SBC engine fit.

A wide-area flanged head that avoids valve-train removal for cylinder-head retorquing is the defining feature of the ARP 134-3703. Its 180,000 psi rating and compact 12-point heads add concrete strength and access details for builders evaluating replacement fasteners.

The wide-area flange is stated to eliminate the need for valve-train removal to retorque the cylinder head, which can simplify that maintenance step. Compact 12-point heads provide the specified head format, and hardened parallel-ground washers come with the kit. ARP also lists a 180,000 psi rating, described as 15% stronger than Grade 8 hardware. These details help buyers weigh retorquing access, included hardware, and strength when checking compatibility.

Skip it if you need a kit explicitly listing SBC engine displacements; BeoneYuu 134-3601 names engines from 262 through 400.

This suits builders who value retorquing access, compact 12-point heads, and included hardened washers. Check the engine-specific fit before buying, as the supplied listing does not name an SBC displacement range.

#3 · Washers Included

3. Fekuar 134-3601 Set

Best for: Rated chromoly SBC bolt buyers.

Why it ranks #3: This 134-3601 kit names several SBC engine sizes, including 350, 383, and 400, and explicitly includes washers with chromoly bolts.

A stated 170,000 psi rating gives the Fekuar bolt set a concrete strength specification for buyers comparing SBC head hardware. The listing also identifies chromoly construction, black-oxide finish, and included washers, connecting its material and kit contents to practical selection and installation checks.

Compatibility is listed for 283, 302, 305, 307, 327, 350, 383, and 400 engines, helping owners compare their displacement with the stated range. Chromoly material and a 170,000 psi rating provide defined construction details, while included washers mean buyers can account for them as part of the kit during assembly. The hex-head style is also specified, giving another useful check for tool access and hardware matching.

Skip it if you need stated coverage for 262 and 265 SBC engines; SDYYDS S96-005 lists both displacements.

This suits SBC builders whose engines fall within the listed range and who want stated chromoly construction, a strength rating, and washers. Its listed applications start at 283, so check displacement and head fit carefully.

4. ARP 134-3601 Bolt Kit

• Material: Stainless Steel
• Thread Size: M11x1.5
• Fastener Size: 0.875 in

Best for: ARP stainless hex-head kit buyers.

Why it ranks #4: The listing calls it an SB Chevy hex-head bolt kit and identifies model 134-3601, but gives conflicting fastener dimensions that need verification.

Stainless-steel material paired with a hex-head style defines this ARP 134-3601 kit for shoppers comparing fastener construction and installation format. Its specifications also list a right-hand thread and a 1/2-inch size name, giving buyers specific details to compare with their SBC build.

The included-components field identifies an SB Chevy hex-head bolt kit, while the stainless-steel specification gives a material detail for buyers evaluating their hardware options. Right-hand thread and the listed 1/2-inch size name provide additional checkpoints for matching the kit to an engine setup. Since the listing also gives an M11x1.5 thread size, compare the complete specifications with the required fasteners before installation rather than relying on the model number alone.

Skip it if you need a kit listing a 170,000 psi rating and included washers; Fekuar’s black SBC set specifies both.

This is for buyers seeking an ARP SB Chevy hex-head kit with stainless-steel material and right-hand threads. Compare its listed size details against the engine’s requirements, particularly before using it with aluminum heads.

5. BeoneYuu 134-3601 Set

• Material: Alloy Steel
• Thread Size: #3-48
• Fastener Size: 3/16-48

Best for: Broad-displacement SBC replacement kit.

Why it ranks #5: It lists SBC engine compatibility from 262 through 400 and chromoly construction, but its listed thread and fastener dimensions appear inconsistent.

A stated range covering Chevy 262 through 400 SBC engines makes this BeoneYuu bolt set useful to shoppers checking several common small-block displacements. The listing also names chromoly construction and a black-oxide exterior, giving buyers material and finish details to consider alongside engine coverage.

The compatibility list includes 262, 265, 283, 302, 305, 307, 327, 350, and 400 engines, which helps owners compare their displacement directly with the stated applications. Chromoly is identified as the material and black oxide as the exterior finish, so those specifications provide clear checkpoints when selecting replacement hardware. The listing gives a flat head style as well; confirm the complete fastener details for the particular engine and head setup.

Skip it if you want an ARP kit with a stated 180,000 psi rating and retorquing-friendly flanged heads; ARP 134-3703 provides those details.

This fits an SBC owner whose displacement appears in the stated range and who values listed chromoly construction and black oxide. Resolve the thread-specification discrepancy and confirm the application before installing it on aluminum heads.

#6

6. SDYYDS 134-3601 Set

Best for: SBC displacement-range shoppers.

Why it ranks #6: The listing names SBC engines from 262 through 400 and chromoly steel, but offers limited dimensional detail for checking fit.

Coverage for nine named Chevy small-block displacements is the practical draw of this SDYYDS 34-piece set. Its listing spans 262 through 400 cubic inches and identifies chromoly steel with a black-oxide coating, enabling buyers to compare both engine range and stated construction in one place.

The compatibility list covers 262, 265, 283, 302, 305, 307, 327, 350, and 400 SBC engines, letting owners check their displacement against the advertised range. Chromoly steel and a black-oxide coating are named as construction details, which help buyers assess the specified material and finish for their build. The description calls the set a direct fit and advises checking vehicle specifications, so verify the exact engine and head combination before assembly.

Skip it if you require a stated fastener rating of 170,000 psi; Fekuar’s black SBC bolt set lists that figure.

This suits an owner of one of the listed SBC displacements seeking a multi-piece chromoly set with black oxide. Check the exact engine and head specifications; the listing gives no numerical strength rating to compare.

#7

7. Edelbrock 85502 Kit

• Material: Aluminum
• Thread Size: 1/4-20

Best for: Edelbrock SBC kit seekers.

Why it ranks #7: The E-Series kit is identified for SBC use, but its specifications list aluminum material and a 1/4-20 thread size without head-bolt dimensions.

Edelbrock names this product an E-Series Head Bolt Kit for SBC, giving Small Block Chevy buyers a brand- and application-specific starting point. Its stock size designation helps frame the intended size category, while the hex-head style offers a recognizable format when comparing hardware for an engine build.

The SBC designation ties the kit to Small Block Chevy applications, while stock size gives buyers a size category to check against their existing setup. The specifications list a hex screw-head style, which is a useful installation detail when comparing tool access and hardware format. Edelbrock identifies the product as mechanical fasteners, but the provided information does not establish a particular aluminum-head fitment or bolt strength, so match it carefully to the engine and head requirements.

Skip it if you need stated chromoly construction and a 170,000 psi rating; Fekuar’s SBC set lists both details.

This is for SBC owners seeking an Edelbrock E-Series kit in the listed stock size and hex format. Confirm that the kit matches the specific heads and fastener requirements, since the listing does not provide a strength rating.

#8

8. ARP 134-3610 Head Bolt Kit

• Material: Stainless Steel
• Thread Size: M10 x 1.5
• Fastener Size: M10 x 1.5

Best for: LS6-specific ARP kit shoppers.

Why it ranks #8: Although it is an ARP head-bolt kit, the listing identifies included components as an SB Chevy LS6 hex-head kit, not a general SBC application.

The LS6 identification is the defining detail of the ARP 134-3610: its included components are described as an SB Chevy LS6 hex-head bolt kit. That specific engine reference helps narrow the search for buyers whose build calls for LS6 hardware, rather than a broadly listed SBC kit.

Stainless-steel material and a right-hand thread are both stated in the specifications, giving buyers concrete details to check against their build and installation requirements. The listing also names M10 x 1.5 as the thread size and describes flat head style, while the included-components field specifies an LS6 hex-head kit. Because those descriptions differ on head style, review the actual application and hardware details before starting assembly.

Skip it if you need a kit expressly covering the listed 262–400 SBC engines; BeoneYuu’s 134-3601 names those displacements.

This is a candidate for buyers matching an LS6 application who want ARP hardware and can resolve the listing’s differing head-style descriptions. Its specific LS6 designation makes it a narrower choice than broad-displacement SBC kits.

#9

9. ARP 154-3607 Head Bolt Kit

• Material: Aluminum, Iron

Best for: Ford Man O’War head applications.

Why it ranks #9: Its description specifies a Ford water-pump and Man-O-War iron-block/aluminum-head application, so it does not match the SBC use case.

The SB Ford Man O’War application is the crucial distinction of this ARP 154-3607 kit, which is described for an iron block with a Man O’War aluminum head. That explicit aluminum-head reference can help Ford builders identify its intended combination, rather than mistaking it for an SBC kit.

The product description specifies an SB Ford Man O’War iron block and Man O’War aluminum head, making the intended engine combination central to fit selection. Aluminum and iron are both listed as materials, and the specifications identify a right-hand thread. These details support checking the block-and-head pairing and thread direction before assembly. Despite appearing in an SBC roundup, its stated application is Ford, so it should not be selected as Chevy small-block hardware.

Skip it if you are assembling an SBC; ARP 134-3601 is identified as an SB Chevy hex-head bolt kit.

This is for a Ford SB Man O’War builder pairing the specified iron block with a Man O’War aluminum head. It is not an SBC choice, so engine family is the key fit boundary.
