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

If you're rebuilding the top end of your Chevrolet Small Block engine and need reliable exhaust valves for racing applications, this Manley Race Series kit is a solid option. These valves are built to handle the stress of engines running up to 8000 RPM, making them a good choice for drag, bracket, or oval track use.

Each exhaust valve is made from high-quality stainless steel, which is known for its durability. They also feature chrome-plated stems and hard tips to resist wear over time, especially important in high-performance engines. The under-head areas are swirl polished and the combustion faces are fully machined. This design helps optimize airflow into the cylinder and can contribute to better combustion efficiency. Manley specifically recommends these for use in alcohol-fueled engines, where they've shown reliable performance.

This kit includes exhaust valves with a 1.500-inch head diameter and a 5.035-inch overall length, with a 0.3415-inch stem diameter. Make sure these dimensions match your cylinder head port size and valve guide specifications.
