The COMP Cams Sportsman stainless steel exhaust valve is listed with a 1.880" diameter and 11/32" stem, offered for BBC exhaust service with .100" added length. Forged from 21-4N high-strength steel and featuring 50 HRc hardened tips, these valves use hard chrome-plated stems with proprietary oil-retention surfacing to improve durability. High-flow underhead fillet relief and swirl polishing raise airflow and reduce radial crack propagation in hydraulic, mechanical and roller lifter applications.
