Ferrea Chevrolet LS1 1.6in 0.313in 4.915in 15 Deg S-Flo Rad Grv Super Alloy Exhaust Valve - Set of 8

Ferrea is known for making strong valvetrain components, and these Super Alloy exhaust valves for Chevrolet LS1 engines are a prime example. If you're rebuilding the top end of your LS1, these valves are built to handle the demands of performance applications. They feature a 1.6-inch face diameter and a 4.915-inch overall length, designed to fit precisely within the LS1 cylinder head.

These valves are constructed from a Super Alloy material, which is chosen for its ability to withstand high temperatures and stresses commonly found in performance V8 engines. The S-Flo design with radial grooves helps improve airflow into the combustion chamber, contributing to better engine breathing and performance. The 15-degree seat angle is standard for many LS heads, ensuring a good seal when paired with appropriate valve seats.

This set includes eight valves, enough for a complete engine. When installing, ensure your valve guides and seats are in good condition to get the most out of these well-made components.
