Description

Featuring precision tolerances and superior final machining, COMP Cams Sportsman stainless steel valves offer outstanding performance and durability for high-rpm, high-horsepower engines. They are manufactured from 21-4N high-strength, one-piece stainless steel. They also feature a chrome polished stem, hardened tips, and high-flow underhead for minimum flow restriction. Recommended for hydraulic, mechanical, or roller lifter camshaft cylinder heads, COMP Cams Sportsman stainless steel valves provide you with the reliability and performance that you require.

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.
