Description

The Manley Performance Race Master exhaust valves are designed for high-performance street, bracket, oval track, and drag racing engines operating under 8000 RPM. These valves are constructed from XH-426 stainless steel, featuring chrome stems and hardened tips for durability. They are swirl-polished and fully machined for optimal airflow and combustion efficiency.

Each valve measures 31.0mm at the head diameter and has a 0.2345-inch stem diameter. For triple groove applications, factory locks must be used, or Manley's Bead Loc® system can be employed with their single radius groove.
