SBC 195cc Enforcer Cyl. Head A/P 64cc Assembled

The SBC 195cc Enforcer Cylinder Head (A/P, 64cc chamber) from Air Flow Research is purpose-built for small block Chevy engine builders and performance mechanics seeking maximum intake flow without sacrificing reliability or drivability. This assembled cylinder head is engineered for street and mild competition applications where responsive power delivery and consistent cylinder-to-cylinder balance matter. Whether you're upgrading a classic hot rod, improving a street performance engine, or building a weekend warrior, the Enforcer head delivers the breathing capacity modern fuel injection and carbureted systems demand.

The 195cc intake port volume provides excellent mid-range torque and peak horsepower characteristics for typical small block Chevy applications ranging from 350 to 406 cubic inches. The 64cc combustion chamber is optimized for compression ratio compatibility across most popular stroker and standard displacement combinations, while the 1.580-inch valve springs deliver consistent sealing at elevated RPM. Dual 2.020-inch intake and 1.600-inch exhaust valves with angle plug configuration ensure efficient scavenging and fuel mixture control. Cast aluminum construction keeps weight at 29.23 lbs per head, reducing overall engine mass while maintaining the durability required for sustained performance driving.

This Enforcer cylinder head assembly is ideal for builders targeting 400–500+ horsepower platforms without requiring exotic porting, exotic fuel systems, or extensive tuning expertise. Installation requires standard small block Chevy intake and exhaust manifold compatibility, along with appropriate gasket selection for your specific block and intake configuration. The pre-assembled design eliminates valve train guesswork and ensures proper spring seat pressure and pushrod geometry from day one. Pair this head with quality roller rocker arms, quality pushrods, and precise ignition tuning for maximum reliability and street manners.
