    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 Street Master Series valves are the perfect choice. These dependable valves are also offered in the Street Master Street Flo (Pro Flo undercut stem) versions providing significant flow gains without head porting. All valves in both these series feature chrome stems, hard tips, swirl polished underhead areas, and fully machined combustion faces.

    Features:
  • Superior Stainless Steel (XH-424 Exhaust and NK-841 Intake)
  • Offers Better Fatigue Strength than competitors' offerings
  • Chrome Stems and Hard Tips
  • Street Master (Straight Stem) and Street Master Street Flo (Pro Flo Undercut Stem) Shapes Available
  • Swirl Polished and Fully Machined
