• Weight: 0.27 g

Best for: Compact-chamber flat-tappet builds.

Why it ranks #10: This is a complete single head with a 54cc chamber and 170cc intake runner, but its listed 454-O designation is less directly matched to the broader Big Block Chevy 454 choices.

A 54cc combustion chamber defines this Edelbrock head’s high-compression configuration, giving builders a clear chamber figure to assess for a 454 setup. It is a complete single for hydraulic flat tappets, with 170cc intake and 60cc exhaust runners; this is one head, not a pair.

The complete-single format is important when planning the purchase and installation: the listing supplies one head rather than a pair. Hydraulic flat-tappet compatibility identifies its valvetrain type, while the 54cc chamber and 170cc intake runner set specific dimensions for a combination check. A 60cc exhaust runner and 1.94-inch intake and 1.55-inch exhaust valves add further sizing information. The listing names the product for 454-O use, making engine configuration and quantity essential selection points.
