COMP Cams Engine Intake Valve 6004-1

COMP Cams Sportsman Stainless Steel Valves are available in a variety of diameters and stem lengths for street/competition engines. Made from 21-4N forged high-strength steel alloy with 50 HRc minimum hard tips (eliminates the need for a lash cap), these valves are state-of-the-art, delivering tremendous performance and durability. Recommended for all hydraulic, mechanical and roller lifter applications, these valves feature hard chrome-plated 11/32-inch stems with proprietary oil retention surfacing, not thin flash plating. To increase flow without increasing the valve diameter, high flow underhead fillet relief was designed in. In addition, the swirl-polished fillets generate a higher flow rate with reduced radial crack propagation, increasing their resistance to failure.
