piece Stainless Steel Stellite Tipped Impregnated Valves
All Black Diamond Stainless Steel Valves are impregnated by a special German
process to .002" deep with a .0002" surface build-up to improve wear properties
and reduce friction. This process provides resistance to corrosion and
wear that is superior to that developed by a hard chromium and electrolysis
nickel plating. These valves are light and the profiles provide excellent
We use these valves for building stock and race engines.
