Ferrea Chevy SB 1.625in 11/32 5.160in 0.25in 14 Deg S-Flo +.200 Comp Plus Exhaust Valve - Set of 8

If you're rebuilding the top end of your Chevy Small Block engine, these Ferrea Comp Plus exhaust valves are a solid option. This set includes eight valves, each measuring 1.625 inches in diameter with a 5.160-inch length. They are designed for a 11/32-inch stem and feature a 14-degree S-Flo seat angle, which helps improve airflow into the cylinder.

These valves are built with durability in mind, featuring a +.200 inch compression length that can be beneficial for certain camshaft profiles or cylinder head combinations. The S-Flo design is a notable feature that Ferrea uses to help reduce swirl and improve the flow characteristics of the exhaust port. This can contribute to a more efficient burn and potentially better engine performance.
