LSX 210cc Enforcer Cyl Head 64cc As Cast Assem.

The AIR FLOW RESEARCH LSX 210cc Enforcer Cylinder Head is a high-flow, as-cast assembled unit engineered for LS-series engine builds targeting significant power gains. This 210cc intake port design delivers superior air velocity and cylinder filling characteristics, making it a preferred choice for performance engine builders and enthusiasts pursuing aggressive displacement and horsepower targets on GM LS platforms.

Key specifications reflect AFR's precision engineering: the 64cc combustion chamber optimizes compression ratio and spark plug positioning, while the 2.000-inch intake valves and 1.570-inch exhaust valves maximize flow paths for both induction and scavenging. The 1.290-inch valve springs provide robust control over valve events at elevated RPM, critical for maintaining reliability in high-performance applications. The angle-plug design improves ignition characteristics and allows for smaller, more efficient chamber geometry compared to conventional straight-plug alternatives. Cast aluminum construction balances durability with thermal properties essential for sustained high-output operation.

This cylinder head assembly serves LS engine builders, performance tuners, and enthusiasts developing street or competition powerplants. Whether for naturally aspirated builds targeting high-RPM horsepower or forced-induction platforms requiring improved volumetric efficiency, the 210cc Enforcer head delivers the flow characteristics and chamber design necessary for top-tier performance. Assembled condition eliminates core machine work and reduces build time, allowing immediate integration into engine assembly sequences.

AFR cylinder heads are recognized within the performance engine community for consistent casting quality and flow-tested performance. The Enforcer line specifically targets the intermediate to advanced builder seeking proven flow numbers without compromise on valve events or spring pressures. Verify compatibility with your specific LS block variant and confirm any machine work required for your particular intake manifold and accessory configuration before installation.
