Manley Chevrolet Small Block Exhaust Valve Kit - 1.600in Head Dia. 5.540in O/A Length, 0.3110in Stem

This kit includes Manley Race Series exhaust valves designed for Chevrolet Small Block engines. These valves are built for demanding applications, including bracket, drag, and oval track racing, especially for engines running under 8000 RPM. They are constructed from high-quality stainless steel, specifically XH-426 for the exhaust valves, which offers excellent durability.

You'll find these valves feature chrome stems and hard tips, adding to their overall longevity and resistance to wear. The under-head areas are swirl polished and the combustion faces are fully machined. This design work helps optimize airflow into the cylinder and improve combustion efficiency. Manley also recommends these specific exhaust valves for use in alcohol-fueled engines, where they stand up well to the conditions.

These are a solid option if you're rebuilding the top end of your Chevrolet Small Block and need reliable exhaust valves that can handle higher RPMs and specific fuel types.
