Ferrea Chevy SB 1.625in 11/32in 5.35in 14 Deg S-Flo +.400 Competition Plus Exhaust Valve - Set of 8

These Ferrea Competition Plus exhaust valves are built for Chevy small-block engines, featuring a 1.625-inch face diameter and a 11/32-inch stem. The 5.35-inch overall length is designed to work with the +.400-inch extended length, which is often needed when using higher lift camshafts or different cylinder head configurations. The S-Flo design helps improve airflow by reducing valve shrouding in the combustion chamber.

Constructed from high-grade steel, these valves are heat-treated for improved durability and resistance to wear under demanding conditions. The 14-degree seat angle is a common specification that works well with many cylinder head designs. This set includes eight valves, enough for a complete V8 engine rebuild.
