Manley Performance Sport Compact stainless steel valves utilize our exceptional alloy known as 'Race Series' and are manufactured to the highest quality standards.
Designed to outflow and outperform all others, Manley valves excel even in the most severe environments.
Featuring gorgeous yet durable chrome stems, swirl polished under heads, fully hardened tips, completely machined combustion faces, closely controlled margin heights, and exact stem to seat concentricity, Manley stainless valves render a finished product that is unsurpassed.
Typically built with our original 'Pro-Flo' design, Manley intake valves reduce the stem diameter in the fillet area for increased airflow while also reducing valve weight.
In certain specific applications, our 'Extreme Duty' exhaust material is offered by Manley.
Our 'Extremealloy' alloy provides more hot hardness and high temperature strength than our competitors' offerings.
This alloy is ideal for extremely high boosted applications where exhaust gas temperatures reach seemingly unthinkable levels.
Suitable for all applications, Manley stainless valves range from the mild street performer to the jaw dropping 1000+ horsepower race cars competing at the drag strip or drifting events.
