Product Details

If you're rebuilding the top end of your Ford 351 Cleveland engine, especially for racing applications, these Manley exhaust valves are a solid choice. They're built to handle the stress of engines running up to 8000 RPM, making them suitable for bracket, drag, or oval track use. The key here is the material and construction designed for longevity under demanding conditions.

These valves are made from high-quality stainless steel, which is crucial for resisting the heat and stress that exhaust valves endure. They also feature chrome stems and hard tips, adding extra wear resistance to the parts that move the most. The under-head areas are swirl polished and the combustion faces are fully machined. This attention to detail helps optimize airflow into the cylinder and can contribute to better combustion efficiency, which is important when you're pushing an engine hard.

Manley offers these in different shapes, like Race Master or Race Flo, so you can pick the best one for your specific engine build. They're also recommended for alcohol-fueled engines, which run hotter and require robust components. This kit includes the exhaust valves you need to get your 351 Cleveland breathing right again.
