Valves Race Series Exhaust Set of 8 Manley Performance Sport Compact stainless steel valves utilize our exceptional Race Series alloy and are manufactured to the highest quality standards.
Designed to outflow and outperform all others in the most severe environments, Manley valves feature gorgeous yet durable chrome stems, swirl polished underheads, fully hardened tips, completely machined combustion faces, closely controlled margin heights, and exact stem to seat concentricity to 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 but also less valve weight.
In certain specific applications, our Extreme Duty exhaust material is offered by Manley.
Our Extreme alloy offers more hot hardness and high temperature strength than competitors' offerings.
This alloy is ideal for extremely high boosted applications where exhaust gas temperatures reach what seem like 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.
