Manley Chevrolet Small Block Exhaust Valve Kit - 1.600in Head Dia. 5.140in O/A Length, 0.3110in Stem

Manley Performance is well-known for making strong engine components for racing applications. If you're rebuilding the top end of your Chevrolet Small Block engine, especially for demanding use under 8000 RPM, these exhaust valves are a solid option. They are built from stainless steel, which holds up well to the heat and stress of combustion.

These valves feature chrome stems and hard tips, adding to their wear resistance and overall lifespan. The under-head areas are swirl polished to help smooth airflow into the cylinder, and the combustion faces are fully machined. This attention to detail helps optimize how efficiently your engine breathes and burns fuel. They are also recommended for use in alcohol-fueled engines, where they offer reliable performance.

This kit includes exhaust valves with a 1.600-inch head diameter, a 5.140-inch overall length, and a 0.3110-inch stem diameter. If you're looking for well-built valves for a performance build, these are a popular choice.
