About this part

Product Details

If you're rebuilding the top end of a Chrysler Small Block engine and need valves that can handle some serious work, these Manley Severe Duty Exhaust Valves are a solid option. They're built for engines running up to 8000 RPM, making them a great choice for drag racing, bracket racing, or oval track applications where durability and performance are key.

These valves are made from stainless steel, which is a strong material that holds up well over time. They also feature chrome stems and hard tips, adding extra wear resistance where it counts. The under-head area is swirl-polished and the combustion faces are fully machined. This design helps improve airflow into the cylinder, which can make a difference in how efficiently your engine burns fuel, especially if you're running alcohol fuels, as these are recommended for that type of application.

This set includes eight exhaust valves, each with a 1.625-inch head diameter and a .3715-inch stem diameter. They're designed to fit right into your existing Chrysler Small Block cylinder heads.
