Product Details
These Manley Race Series exhaust valves are built from XH-426 stainless steel, a strong material chosen for its ability to handle the heat and stress inside a performance engine. They measure 1.600 inches across the head and are 5.065 inches long overall, with a 0.3415-inch stem diameter, making them a solid choice for Chevrolet small block engines, especially those running up to 8000 RPM.
You'll notice the chrome stems and hard tips, which are there to help them last longer and resist wear, especially in demanding applications like bracket, drag, or oval track racing. The under-head area is swirl polished to help smooth airflow, and the combustion face is fully machined. These are also recommended for alcohol-fueled engines, where they offer reliable performance.
