About this part

Product Details

Manley Performance offers these Street Series exhaust valves for your Chevrolet Small Block engine. If you're rebuilding the top end or looking to improve the airflow on a stock or mildly modified street engine, these valves are a solid option. They are crafted from high-grade stainless steel, which means they'll hold up well over time and resist corrosion.

These valves feature chrome stems and hard tips, adding to their durability and wear resistance. The areas under the head are swirl polished, and the combustion faces are fully machined. This attention to detail helps improve airflow into the combustion chamber, which can lead to better engine efficiency. The overall length is 4.911 inches with a 1.500-inch head diameter and a 0.3415-inch stem diameter.
