Black Diamond Exhaust Valve Kibblewhite One-piece stainless steel. Stellite tipped. Impregnated by a special German process .002 in. deep and .0002 in. surface buildup 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 forging of either EV8 stainless steel or Inconel-751. Two proven heat and corrosion-resistant materials. Fully CNC-machined and hard chromed with a 360 Degree anode which produces nearly perfect hard chrome. Set contains springs and titanium upper collars and lower collars as required.
