BBC H/P 1.880in Exhaust Valves

The FERREA BBC H/P 1.880 inch Exhaust Valves (set of 8) are designed for serious big-block Chevrolet performance builds, providing the necessary flow characteristics and durability for high-performance applications. These valves are essential for both street engines and competition powerplants, ensuring optimal cylinder head efficiency and exhaust scavenging at elevated RPM.

Engineered to withstand the thermal cycling and combustion pressures of forced induction and high-rev applications, these valves feature a precisely sized 1.880 inch head diameter that optimizes the valve-to-port relationship. This design enhances gas flow velocity and minimizes restrictions during the exhaust stroke, crucial for maximizing engine performance.

Engine builders upgrading from factory components will find these valves indispensable, especially when supporting larger carburetors, nitrous systems, or supercharger modifications. Proper installation requires valve seat machining and precise height adjustments to ensure maximum performance and longevity.
