Ferrea Chevrolet LS1 1.55in 0.313in 4.915in 15 Deg S-Flo Rad Grv Super Alloy Exhaust Valve- Set of 8

This set includes eight Ferrea Super Alloy exhaust valves, specifically made for Chevrolet LS1 engines. These valves are designed to handle the demands of high-performance LS1 builds, helping to improve the flow of exhaust gases out of your engine. The S-Flo design and radial groove are features that contribute to better valve seating and sealing.

Crafted from a special super alloy, these valves offer improved durability and resistance to the high temperatures found in performance engines. The 1.55-inch face diameter and 4.915-inch overall length are key dimensions for proper fitment and function within the LS1 cylinder head. The 15-degree seat angle is standard for many LS applications, ensuring compatibility with the valve seats.

If you're rebuilding or upgrading your LS1 engine's top end, these valves are a solid option for ensuring reliable performance and proper sealing. They are designed to be a direct replacement for your stock exhaust valves, making installation straightforward for someone familiar with engine work.
