Big Block Ford Black Lightning Racing Valves
Black Lightning Racing valves are forged from premium 21-4N stainless steel. They have undercut steps and swirl polished heads to help the flow of both fuel and exhaust gasses going into and exiting the engine combustion chamber. The heads are also designed with thinner margins to reduce weight and inertia.
These valves also feature a unique nitride coating that is better than chrome for higher revving race engines. They produce less friction, have exceptional wear resistance and increased strength and ductility.
All QualFast Performance Valves are sold in matched sets of 8. To order the full set, be sure to enter 8 for the quantity.
