COMP Cams Sportsman stainless steel exhaust valves (1.600" x 11/32" standard length) are forged from 21-4N high-strength alloy with hardened tips and chrome-plated stems that help avoid the need for lash caps. Designed with swirl-polished fillets and high-flow underhead relief, these valves reduce flow restriction and improve resistance to radial crack propagation for street and competition valve train applications.
