Manley Severe Duty Valves are designed for high-performance and racing applications. Exhaust valves are manufactured from XH-428 material, while Intake valves are manufactured from NK-844 material.
Severe Duty Valves have undergone rigorous fatigue testing. During normal operation, valves experience 20,000 to 25,000 lbs of applied stress. When valves bounce on the seat, stress increases to 40,000 to 60,000 lbs.
- Designed for high-temperature gasoline engines
