About this part

Product Details

If you're rebuilding the top end of a Chevy Small Block engine, these Manley Race Master exhaust valves are a solid option. They're designed for engines that see a lot of action, especially those running up to 8000 RPM, like you'd find in bracket, drag, or oval track racing. These are the exhaust valves, and they're built to handle the heat and stress that comes with combustion.

Manley makes these from a high-quality stainless steel, which is key for resisting the corrosive effects of exhaust gases and ensuring they last. The stems are chromed and have hard tips, adding even more wear resistance where it counts. You'll also notice the under-head area is swirl polished to help smooth out airflow, and the combustion face is fully machined. This attention to detail helps optimize how efficiently your engine breathes and burns fuel. They're even recommended for alcohol-fueled engines, which tells you something about their robust design.

This set includes eight exhaust valves, which is what you'll need for a standard V8. They are the 'Race Master' straight stem style, designed to fit specific cylinder head port configurations.
