What is the main benefit of the swirl-polished fillets and underhead relief on these valves?

These design features are intended to increase airflow through the intake port without requiring a larger valve diameter. This can lead to improved engine performance.

Do these valves require a lash cap?

Product Details

If you're rebuilding the top end of a Chevrolet Small Block engine for street or competition use, new intake valves are a smart move. These COMP Cams Sportsman valves are made from a strong 21-4N forged steel alloy, built to handle the demands of performance engines. They feature a 2.020-inch head diameter and a 4.911-inch length, designed to fit a wide range of Small Block Chevy applications.

These valves are well-built with a hard chrome-plated stem that's 11/32 inches in diameter, and the tip is hardened to 50 HRc, so you don't need a lash cap. COMP Cams also put a lot of thought into airflow. They've included a high-flow underhead fillet relief and swirl-polished fillets. This design helps increase airflow without needing a larger valve diameter, and it also makes the valve more resistant to failure over time.

This is a solid option for anyone looking to get more performance out of their Small Block Chevy, whether you're using hydraulic, mechanical, or roller lifters. They fit a broad range of vehicles, from classic Camaros and Corvettes to C10 trucks and Impalas.
