About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these Race Flo exhaust valves are a great example of that. If you're rebuilding a Chevy small block engine and need a set of reliable exhaust valves, this set of eight is built to handle the heat and stress of performance applications, especially those running alcohol fuels.

These valves are made from stainless steel, which is a solid choice for exhaust valves because it holds up well to high temperatures. They also feature chrome stems and hard tips, adding extra wear resistance where it counts. The under-head areas are swirl polished and the combustion faces are fully machined. This design helps improve airflow into the cylinder and can contribute to better combustion efficiency, especially in engines that operate under 8000 RPM.

This particular set is the Race Flo shape, which is designed to optimize airflow for specific racing engine requirements. If you're working on a bracket car, drag car, or oval track racer, these valves are a well-built option to consider for your build.
