Overview

The Supertech Exhaust Valve Set is a set of 12 Inconel performance exhaust valves. These valves are designed as a starting point for 30V cylinder head builds and offer a more reliable replacement for stock valves. The Inconel material provides superior heat resistance, making them suitable for turbo and nitrous applications.

Show original supplier description

The Supertech Exhaust Valve Set includes 12 Inconel performance exhaust valves, serving as an excellent foundation for any 30V cylinder head build. These valves are a superior alternative to OEM stainless steel or sodium-filled exhaust valves, which are prone to crumbling. The Inconel construction offers significantly greater resistance to heat and wear compared to stock valves. This makes them an ideal choice for demanding applications such as those involving turbochargers and nitrous oxide systems. For builders aiming for the absolute highest performance levels, Supertech also offers these valves in a +1mm oversize option, which requires machining for maximum flow potential. Additionally, single groove keeper setups are available for engines operating at extremely high RPMs. This single groove design secures the valve shaft directly, providing a more robust solution than traditional multi-groove retention methods.
