    Manufacturer's Part Number:

    Manley Performance is indisputably a leading manufacturer of performance and racing components in the world. The reason for Manley's overwhelming success is simple: Quality. Manley offers the best materials in the industry - exclusive materials that other manufacturers do not possess. Manley's valve stems are hard coated with .0002'' thick chrome rather than a few millionths of flash. Manley's hard valve tips are superior to competitors' puddled ''stellite'' which can crack and erode off the stem. Manley's valve head and under head shapes have been in the forefront of the quest for improved flow since the late 1960's.

    Designed for the enthusiast preparing a stock or mildly modified street engine, or a bracket racer seeking maximum value for his dollar, the Budget Performance Series valves are the perfect choice. This valve is offered with a swirl polished stem radii providing some flow advantages without head porting. This series features chrome stems, hard tips, swirl polished underhead areas, and fully machined combustion faces.

  • Superior Stainless for High Temperature Gasoline Engines
  • Offers Better Fatigue Strength than competitors' offerings
  • Chrome Stems and Hard Tips
  • Swirl Polished and Fully Machined
