About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these Race Master exhaust valves are a prime example. If you're rebuilding the top end of your 2009 and up Gen III Hemi 5.7L, these are built to handle the heat and stress of performance driving, especially if you're running alcohol fuels.

These valves are made from a high-quality stainless steel that holds up well over time. They feature chrome stems and hard tips, which adds to their wear resistance, meaning they'll keep sealing properly for a long time. The under-head areas are swirl polished to help air move smoothly, and the combustion faces are fully machined. This design helps optimize airflow and combustion efficiency, which is important for getting the most out of your engine.

You'll want to make sure these are the right fit for your specific build, as Manley offers different shapes like Race Master (straight stem) and Race Flo. For alcohol engines, these exhaust valves are a recommended choice for reliable performance.
