About this part

Product Details

If you're rebuilding the top end of your Chrysler Hemi 6.4L engine, especially for racing applications, you need valves that can handle the stress. These Manley Race Master exhaust valves are built for engines running up to 8000 RPM, making them a solid option for bracket, drag, or oval track use.

They're made from a high-quality stainless steel that's tough enough for demanding conditions. The stems are chromed and feature hard tips to resist wear over time, and the under-head areas are swirl polished while the combustion faces are fully machined. This design helps optimize airflow into the cylinder, which can improve how efficiently your engine burns fuel and makes power. Manley also recommends these specific exhaust valves for alcohol-fueled engines, where they've shown reliable performance.

This set includes eight exhaust valves, specifically the Race Master straight stem style, which is a popular choice for many racing engine builds.
