Description

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" 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. Variety of diameters and stem lengths for Street/Competition engines - affordable! Made from 21-4N forged high strength Steel alloy for performance and durability‚ Recommended for all hydraulic, Mechanical and Roller lifter valve trains‚ Chrome plated stem and hardened tip don't require lash cap‚ Spiral polished and high flow underhead machining for maximum flow.

Product Overview

COMP Cams Sportsman Valves are available in a variety of materials, diameters and stem lengths for street and competition engines. The stainless steel valves are made from 21-4N forged steel alloy with 50 HRC minimum hard tips (eliminating lash caps); these valves deliver tremendous performance and durability. The hard chrome-plated 11/32" stems utilize proprietary oil retention surfacing. For extremely high revving LS applications, COMP® engineers developed titanium valves. Weighing 35% less than stainless steel, titanium valves are a must for race applications where valve float is not an option. For high temperature and high boost applications, valves constructed from Inconel superalloy are also available.
