About this part

Product Details

In this set, you get four Manley Race Master exhaust valves, each measuring 42mm with triple grooves. These valves are built for engines that run up to 8000 RPM, making them a solid choice for racing applications like bracket, drag, and oval track. They are specifically recommended for exhaust valves in alcohol-fueled engines, where they can handle demanding conditions reliably.

These valves are made from stainless steel, which gives them a lot of durability. The stems are chromed and have hard tips, adding to their lifespan and resistance to wear. The area under the head is swirl polished, and the combustion faces are fully machined. This design helps optimize airflow and combustion efficiency, which can make a difference in how your engine performs.

You have a choice between the Race Master (straight stem) and Race Flo shapes to best match your engine's specific needs.
