Ferrea Chevy SB 1.6in 11/32in 5.4in 0.25in 12 Deg S-Flo +.500 6000 Series Exhaust Valve - Set of 8

Starting with a 1.6-inch head diameter and a 11/32-inch stem, these Ferrea 6000 Series exhaust valves are built for performance in Chevy small-block engines. The 5.4-inch overall length and a +.500 inch oversize dimension are key specs for rebuilding or upgrading your top end, ensuring a proper fit and improved airflow over stock components.

Ferrea uses their well-known S-Flo design, which features a 12-degree seat angle and a specialized profile to help gases exit the cylinder more efficiently. This can lead to better combustion and a more responsive engine. The valves are constructed from durable materials designed to withstand the heat and stress of exhaust gases, making them a solid option for a performance rebuild where reliability is important.

This set includes eight valves, enough for a complete V8 engine. When rebuilding your engine, ensure you have the correct valve guides and seals to match these performance valves for optimal operation.
