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

The SBC 195cc Enforcer Cylinder Head with 64cc chamber from AIR FLOW RESEARCH is a complete, assembled cylinder head engineered for high-performance small-block Chevy engines demanding superior airflow and combustion efficiency. This is a fully prepared head ready for installation, eliminating machine shop prep time and delivering optimized flow characteristics straight from the box.

The 195 cubic centimeter intake port volume paired with the compact 64cc combustion chamber creates a high-compression geometry that maximizes flame travel and burn rate—critical for consistent detonation control and power development across the RPM band. The 2.020-inch intake and 1.600-inch exhaust valve dimensions are sized for optimal flow velocity without excessive lifting duration, while the 1.290-inch valve springs provide reliable sealing under sustained boost or high-RPM operation. The straight-plug configuration allows flexible ignition system integration, and the aluminum construction keeps rotational mass low, reducing parasitic losses on the crankshaft.

This head addresses the needs of engine builders and performance enthusiasts constructing fuel-injected or carbureted small-block platforms for street, competition, or off-road service. The assembled configuration saves turnaround time for shops and individual builders, while the published flow numbers and chamber design eliminate guesswork in combination selection. Weighing 28.01 pounds, the head integrates readily into existing small-block mounting surfaces and accessory configurations.

AIR FLOW RESEARCH cylinder heads are known in the engine-building community for precise flow mapping and consistent casting quality. The 64cc chamber sizing balances compression ratio flexibility with reliable quench characteristics, allowing builders to dial in desired static compression without excessive piston-to-head clearance concerns on stroker or oversized-bore combinations.
