Brian Crower 30mm EXHAUST Valves (Honda H22) Fashion

Exhaust Valves (BC3031) by Brian Crower®. BC valves are made from one piece forgings, where the head of the valve is forged under a two step process to keep a consistent material grain flow. Intakes are made from EV8 (21-4N) steel. This is the highest grade of steel available and provides the strength to withstand just about any application. BC exhaust valves are made from EV16 (21-8N) or EV8-Nb w for greater strength at higher temperatures. All BC valves are chrome coated for a polished finish, hardened to 52Rc and capable of withstanding temperatures in excess of 1400F.
