This set of eight COMP Cams Sportsman stainless steel exhaust valves is sized for BBC exhaust work with 1.880" heads and 11/32" stems, plus .100" length. Forged 21-4N high-strength steel and 50 HRc hardened tips remove the need for lash caps, while hard chrome-plated stems feature oil-retention surfacing rather than thin plating. Swirl-polished fillets and underhead relief boost flow and reduce radial crack propagation for hydraulic, mechanical and roller lifter valve trains.
