COMP Cams Ss Valve SBC Exh 1.600in 11/32

This is a COMP Cams Sportsman Stainless Steel Exhaust Valve, designed for Chevrolet Small Block engines. It features a 1.600-inch head diameter and a standard 4.911-inch length with an 11/32-inch stem. These valves are built for street and competition use, offering a solid option for engine rebuilds or performance upgrades across a wide range of vehicles, including popular models like the Chevrolet Camaro and C10 Pickup.

Crafted from a 21-4N forged high-strength steel alloy, these valves are made to handle the demands of hydraulic, mechanical, and roller lifter applications. The stems are hard chrome-plated and feature a proprietary oil retention surfacing, meaning you won't need a separate lash cap. COMP Cams also incorporated a high-flow underhead fillet relief and swirl-polished fillets. This design helps increase airflow without needing a larger valve diameter and also improves resistance to cracking, contributing to their durability.
