Ferrea Chevy SB 1.625in 11/32 4.960in 14 Deg S-Flo +.050 Competition Plus Exhaust Valve - Set of 8

When you're rebuilding the top end of your Chevy small block engine, you want parts that can handle the heat and stress. This set includes eight Ferrea Competition Plus exhaust valves, ready to go into your engine. These valves are designed for performance applications, featuring a 1.625-inch head diameter and a 4.960-inch overall length, which is +.050 inches larger than stock to help improve airflow.

Ferrea uses high-quality steel for these valves, heat-treated and polished to ensure they can withstand the demanding conditions inside your engine. The 11/32-inch stem size is standard for many Chevy SB applications, and the 14-degree S-Flo seat angle is a design choice that can help improve flow characteristics. These are well-built valves intended for builders looking for a solid upgrade over stock components for their performance engine builds.
