These Black Diamond complete engine valve kits by noted Californian valvetrain specialist Kibblewhite Precision Machining include valve spring kit, a full set of Black Diamond stainless steel standard size valves, and (where applicable) H.T. steel valve keepers and valve stem seals.
All Kibblewhite Black Diamond brand valves are impregnated by a special process to a depth of .002" with a surface build-up of .0002" - this process improves wear properties, reduces friction and provides resistance to corrosion and wear.
Compatible with leaded and unleaded fuels, they are sold as complete kits for one engine; available for 1970 - 1985 XL and 1984 - 1999 Evolution Big Twins.
