GM LSx 210cc Enforcer Cyl Head 64cc Assembled

The GM LS-Series 210cc Enforcer Cylinder Head is a fully assembled, performance-oriented cylinder head engineered for builders seeking proven flow characteristics and chamber efficiency in LS-platform engine builds. This 64cc combustion chamber head features 2.020-inch intake and 1.600-inch exhaust valves paired with valve springs designed for optimal performance, angle-plug configuration, and aluminum construction—delivering the intake and exhaust flow dynamics demanded by street, road-course, and high-output LS engine applications.

The 210cc intake runner volume balances port velocity with air mass flow, optimizing fuel atomization and combustion efficiency across the RPM band. The 64cc chamber size reduces compression losses and supports controlled detonation margins when tuned for forced-induction or naturally aspirated configurations. The angle-plug design improves flame propagation and combustion consistency, critical for reliable power delivery and consistent ignition timing.

Buyers performing LS engine restorations, performance upgrades, or complete engine builds rely on cylinder head specifications to control compression ratio and intake manifold compatibility. This head accommodates common LS intake manifolds, primarily designed for fuel-injected systems, ensuring compatibility with a wide range of LS engine applications.
