Ferrea Chevrolet BB 1.88in 3/8in 5.45in 15 Deg S-Flo +.100 Competition Plus Exhaust Valve - Set of 8

This set includes eight Ferrea Competition Plus exhaust valves, specifically made for Chevrolet Big Block engines. Each valve features a 1.88-inch head diameter and a 3/8-inch stem, with an overall length of 5.45 inches. These are +.100 inch oversize valves, meaning they are larger than stock and intended for engines that have been machined to accommodate them, often during a rebuild or performance upgrade.

Ferrea's Competition Plus valves are built with high-quality materials designed to handle the demands of performance applications. The S-Flo design helps improve airflow into the cylinder, which can contribute to better engine performance. The +.100 oversize dimension is crucial for engines that have had their valve seats re-machined or replaced, allowing for a fresh sealing surface and optimal compression. These valves are a solid option when you're rebuilding the top end of your Chevrolet Big Block and need reliable components that can stand up to increased stress.
