The COMP Cams Sportsman stainless steel exhaust valve set is a set of eight valves intended for SBC (small-block Chevrolet) exhaust use with 1.500" diameter and 11/32" stems. These valves are forged from 21-4N steel with 50 HRc hardened tips to remove the need for lash caps and hard chrome-plated stems with oil-retention surfacing. Swirl-polished fillets and high-flow underhead relief increase flow while reducing radial crack propagation. Recommended for hydraulic, mechanical and roller lifter valve trains.
