Kibblewhite Black Diamond Exhaust Valve

• One-piece stainless-steel, stellite-tipped valves impregnated by a special nitrided process with .002″ depth and .0002″ surface buildup to improve wear properties and reduce friction

• This process provides resistance to corrosion; wears superior to hard chromium and electrolysis nickel-plating

• Lightweight with profiles that provide excellent flow characteristics

• Compatible with leaded and unleaded fuels and can be run in cast iron- and bronze-type guides at close tolerances for maximum oil control and heat dissipation

• Made in the U.S.A.
