Manley Chrysler 361 Exhaust Valve Kit - 1.740in Head Dia. 5.010in O/A Length, 0.3715in Stem

These Manley Race Series exhaust valves are built from XH-426 stainless steel, a material chosen for its strength and resistance to high temperatures. With a head diameter of 1.740 inches and an overall length of 5.010 inches, they are designed to fit Chrysler 361 engines and handle demanding conditions, especially those found in bracket, drag, and oval track racing where engines often operate under 8000 RPM.

You'll notice the chrome-plated stems and hard tips, which add a layer of wear resistance, helping these valves last longer in your engine. The under-head areas are swirl polished to help smooth airflow into the combustion chamber, and the combustion faces are fully machined. This attention to detail in machining and polishing helps optimize airflow and combustion efficiency, which can make a noticeable difference in engine performance.

Manley offers these valves in different shapes, like the Race Master straight stem or the Race Flo shape, so you can pick the one that best suits your specific engine build. They are also a recommended choice for exhaust valves in alcohol-fueled engines, indicating their robust design for challenging fuel types.
