8mm 1.600 Exhaust Valve SBC/SBF Race

The 8mm 1.600 Exhaust Valve SBC/SBF Race is a precision-engineered cylinder head component designed for serious small-block engine builders pushing maximum RPM and cylinder pressure. This valve is particularly suited for high-revving small-block Chevrolet and Ford race engines, delivering the flow characteristics and durability needed for competitive applications.

Engineered by Air Flow Research (AFR), this valve is specifically designed for race applications where stock exhaust valves may fail under thermal and mechanical stress. With an 8mm stem diameter and a 1.600-inch head, it offers reduced weight compared to factory designs while ensuring effective heat dissipation through the valve seat and guide. The precision grinding and race-spec material composition contribute to optimized exhaust gas scavenging and improved volumetric efficiency at elevated RPM ranges.

Race engine builders will find this component beneficial for both small-block Chevrolet and Ford platforms, making it ideal for engine swaps and versatile competition builds. Proper valve seat preparation and spring rate selection are essential for optimal installation and performance.
