Impregnated by a special German process to improve wear properties and reduce friction. This process provides resistance to corrosion and wear superior to that developed by hard chromium and electrolysis nickel plating. These valves are light and the profiles provide excellent flow characteristics. One-piece stainless steel, stellite tipped. Intake Valve Intake, Head Dia.: 1.950, Stem Dia.: 0.3090, O.A.L.: 3.690, O.E.M.: 18069-65R
