Product Details

If you're rebuilding the top end of a Chrysler 361 engine, these Manley Race Series exhaust valves are a solid option. They're built from stainless steel, which is a strong material that holds up well to the heat and stress of combustion. The specific stainless alloy used here is XH-426, known for its durability in high-performance applications.

These valves feature chrome-plated stems and hard tips, adding extra wear resistance where it counts. The under-head areas are swirl polished to help smooth airflow into the cylinder, and the combustion faces are fully machined for better efficiency. Manley recommends these for engines running up to 8000 RPM, and they're particularly well-suited for use in alcohol-fueled engines where exhaust valves face tough conditions.

This kit includes the exhaust valves with a 1.810-inch head diameter and a 5.010-inch overall length, featuring a 0.3715-inch stem diameter. When rebuilding your engine, using well-made valves like these can make a notable difference in performance and longevity.
