Why it ranks #1: A clearly listed pair of complete aluminum heads fits small-block 350/327/383 applications and specifies 190cc intake runners, 64cc chambers, and a hydraulic flat-tappet line.

A matched pair of aluminum heads with 190cc intake runners and 64cc chambers gives Small Block Chevy 350 owners a defined replacement package. GELUOXI lists 327 and 383 applications as well, so the same stated configuration covers several related engine builds without choosing separate head specifications.

#5 · Best Valve-Spec Detail

5. PUFFIS Aluminum Cylinder Head

Best for: Straight-plug assembled SBC head.

Why it ranks #5: It lists 350 compatibility, a 64cc chamber, 190cc–200cc intake runners, and installed 2.020-inch intake and 1.600-inch exhaust valves.

PUFFIS combines a 64cc chamber with 2.020-inch intake and 1.600-inch exhaust valves in a straight-plug aluminum head for compatible SBC applications. Its stated 327, 350, and 383 fitment and 190cc–200cc intake-runner range give builders useful dimensions for comparing configurations.

The 64cc chamber and 190cc–200cc intake runner range provide a chamber figure and a runner-volume range for assessing an SBC build. PUFFIS also specifies 62cc exhaust runners and lists 2.020-inch intake and 1.600-inch exhaust valves, giving buyers further configuration details.

#6 · Best CNC-Machined Option

6. VEVOR Engine Head Assembly

• Weight: 26.9 lb

Best for: CNC-machined replacement assembly.

Why it ranks #6: Its assembly is listed for SBC 327/350/383, and the description specifies CNC machining of the combustion chamber and intake and exhaust passages.

CNC machining of the combustion chamber and intake and exhaust passages is VEVOR’s defining feature, with the manufacturer describing smoother airflow than standard casting. The aluminum assembly is listed for Small Block Chevrolet 327, 350, and 383 applications, including Corvette, Camaro, and Z06 vehicles.

VEVOR presents this as a replacement cylinder head assembly for resolving head failure or damage, so it speaks to a repair workflow as well as a replacement build. CNC precision machining is specified for the combustion chamber and both passages; the listing connects that process with smoother airflow compared with standard casting. Fitment covers SBC 327, 350, and 383, while the supplied details do not state runner volume, chamber volume, or valve dimensions for configuration comparisons.

#7 · Largest Listed Runner

7. Speedmaster Assembled Cylinder Heads

• Weight: 50.8 lb

Best for: Assembled racing head pair.

Why it ranks #7: The assembled aluminum pair specifies 205cc runners and 64cc chambers, but its legal disclaimer restricts it to racing applications and says it is not for street use.

Installed springs and valves make Speedmaster’s assembled pair a more direct option for a racing build than bare heads requiring those components separately. Its listing specifies 205cc runners, 64cc chambers, and hydraulic flat-tappet configuration for a broad range of Small Block Chevy engines, including the 350.

The assembled format, with springs and valves installed, can reduce the parts-assembly work before installation; the listing also identifies the heads as a bolt-on pair. Its 205cc intake runner and 64cc chamber figures help buyers compare the configuration with their intended engine setup, while hydraulic flat-tappet specification identifies the valvetrain type. Compatibility spans Small Block Chevy 265 through 400 applications, including 350, but the seller explicitly limits use to racing and says they are not for street use.

Skip it if you need heads for a street-driven 350; GELUOXI 129006601 heads list 350 replacement compatibility without a racing-only restriction.

Choose this assembled pair for a Small Block Chevy racing project that benefits from installed valves and springs. Its stated boundary is decisive: the listing says racing applications only, not street use, so it is not a street-car choice.

#8

8. IMOOA Angle Plug Heads

Best for: Angle-plug bare-head pair.

Why it ranks #8: These bare aluminum heads fit small-block 350 applications and offer 205cc runners, 64cc chambers, and an angle-plug configuration.

An angled spark-plug configuration distinguishes IMOOA’s bare aluminum pair from straight-plug options, while its 205cc intake runners and 64cc chambers define the stated head combination. Fitment covers Small Block Chevy engines from 283 through 400, including the 350, giving this pair broad listed SBC application coverage.

The 2.020-inch intake and 1.600-inch exhaust valve diameters provide useful build-planning figures alongside the 205cc intake runner and 64cc combustion chamber. Bronze valve guides and ductile iron valve seats are listed construction details, while the bare-head format means this is not described as an assembled head with installed components. Its angle-plug style and compatibility through SBC 283, 302, 305, 327, 350, 383, and 400 make engine and plug-layout checks important.

Skip it if you need an assembled head with installed valves and springs; Speedmaster PCE281.2010 lists those components as installed.

This pair suits an SBC builder seeking angle-plug bare heads with specified valve sizes and 205cc runners. Its bare format requires assembly planning, and the intended engine must accommodate the listed angled spark-plug configuration.

9. Auto Dynasty Bare Cylinder Heads

• Weight: 44 lb
• Package Dimensions: 22 x 10 x 7 in

Best for: Competition square-port pair.

Why it ranks #9: The pair fits SBC 350 applications up to 1986 and specifies 200cc runners and 68cc chambers, but is marked for competition racetrack use only.

A pair of bare heads with 200cc intake runners and 68cc chambers gives this Auto Dynasty option a defined competition-oriented configuration for small-block builds. The listing also calls out square intake and exhaust ports, plus pre-drilled accessory bolt holes, useful details when planning the head installation.

The 200cc intake runner and 68cc chamber are stated alongside a claim of retaining stock compression for 1970-and-earlier models, giving those builders a specific compatibility point to assess. Pre-drilled accessory bolt holes can simplify accessory mounting, while the three-angle valve seat is another supplied machining detail. These are bare heads, not assembled units, and Auto Dynasty specifically excludes Vortec-style intake manifolds. Its legal disclaimer restricts use to competition racetrack applications.

Skip it if you need a street-use head; VEVOR Engine Cylinder Head Assembly Replacement is listed for SBC 327, 350, and 383 without this racetrack-only restriction.

Consider this pair for a competition-racetrack SBC project that can use its square ports and pre-drilled accessory holes. Avoid it for street or other noncompetition use, and note that it is incompatible with Vortec-style intake manifolds.

#10

10. DNA MOTORING Bare Cylinder Head

• Weight: 21.3 lb
• Package Dimensions: 22 x 10 x 8 in

Best for: Bare-head port specification.

Why it ranks #10: This bare head lists 350 compatibility up to 1986, 200cc runners, and 68cc chambers, but the listing describes a single head rather than a pair.

A 200cc square-port intake and 68cc chamber give this DNA MOTORING bare head a clearly specified airflow and chamber combination for a compatible SBC build. Its straight-plug layout and 23-degree valve angles add useful configuration details for builders comparing head geometry before assembling a 350.

This is a bare aluminum head, so buyers should account for the assembly work that entails rather than expecting the installed springs and valves listed for assembled alternatives. The stated 2.020-inch intake and 1.600-inch exhaust valve diameters, three-angle valve seat, and bronze valve guides provide specific component and seat details for planning the build. Fitment is listed for 302, 327, 350, 383, and 400 small-block engines manufactured in 1986; confirm the application matches that wording.

Skip it if you want a ready-assembled pair; Speedmaster PCE281.2010 lists springs and valves installed.

This head fits a builder who wants specified port, chamber, valve, and guide details while assembling a compatible SBC project. It is bare, and its fitment wording specifies engines manufactured in 1986, so account for both boundaries.
