Manley Chevrolet Small Block Exhaust Valve Kit - 1.500in Head Dia. 5.035in O/A Length, 0.3415in Stem

Manley Performance is well-known for making strong internal engine components. For your Chevrolet Small Block, these Street Series exhaust valves are a solid option if you're looking to improve the performance of a stock or lightly modified engine. They are designed to handle the demands of street use while offering improved airflow over stock valves.

These exhaust valves are made from high-grade stainless steel, which means they'll hold up well over time. The stems are chromed and feature hard tips, adding extra durability and resistance to wear. The areas under the head are swirl polished, and the combustion faces are fully machined. This attention to detail helps improve airflow into the cylinder and can contribute to better combustion efficiency.

This particular kit includes exhaust valves with a 1.500-inch head diameter and an overall length of 5.035 inches, with a 0.3415-inch stem. You can choose from different shapes like Street Master (straight stem) or Street Flo to best suit your engine build.
