These lightweight valves are then impregnated by a very special process .002" deep and a surface build up, to improve wear properties and reduce friction. This process provides resistance to corrosion and wear superior to that developed by hard chromium and electro-less nickel plating. Most valves are available in either stock size with stock or thin stem and with larger head diameter for the high performance engine builder. Twin Cam 2005 to present ZPN Type Stem dia. Head dia.
