COMP Cams Ss Valve LS1 Exh 1.57in 4.930in

COMP Cams is well-known for making performance valvetrain components that help engines run better. If you're working on a GM LS engine, especially in your 1997-2004 Chevrolet Corvette, these Sportsman Stainless Steel Exhaust Valves are a solid option for street or competition builds. They're designed to handle the demands of performance engines and offer a good balance of cost and capability.

These valves are constructed from a 21-4N forged high-strength steel alloy, which gives them the durability needed for performance applications. The stems are hard chrome-plated and feature a special surface treatment that helps retain oil, meaning you won't need a separate lash cap. To help your engine breathe easier, COMP Cams incorporated a high-flow underhead fillet relief and swirl-polished fillets. This design not only increases airflow but also helps reduce the chance of cracks forming, making the valves more resistant to failure.

These valves are recommended for use with hydraulic, mechanical, and roller lifter applications, making them versatile for many LS engine builds. They fit right into LS1 engines and are designed to increase flow without needing a larger valve diameter.
