Product Details
These Manley Race Series exhaust valves start with a 1.575-inch bead diameter, a specific measurement that matters for getting the right fit and flow in your Hemi 5.7L V8. They're built from XH-426 stainless steel, chosen for its ability to stand up to the heat and stress of racing engines running under 8000 RPM. You'll also notice the chrome stems and hard tips, which are there to help them last longer and resist wear, especially important when you're pushing your engine hard.
The design includes swirl-polished areas under the head and fully machined faces. This isn't just about looks; it helps smooth out the airflow as it enters the cylinder, contributing to better combustion efficiency. Manley also recommends these for alcohol-fueled engines, which tells you something about their durability and resistance to the specific conditions those fuels can create. If you're rebuilding the top end of your Hemi and need valves that can handle the demands of bracket, drag, or oval track racing, these are a solid option.
