Product Details
If you're rebuilding the top end of your 1999-2008 Ford Mustang's 4.6L DOHC 4-valve engine, especially for racing applications, these Manley Race Master exhaust valves are a solid choice. They're built to handle the stress of engines running up to 8000 RPM, common in bracket, drag, or oval track racing.
These valves are made from XH-426 stainless steel, which is known for its durability under high heat. The stems are chrome-plated for better wear resistance, and the tips are hardened to last longer. Manley also swirl polishes the area under the head and fully machines the combustion face. This helps improve airflow into the cylinder and makes combustion more efficient, which can make a noticeable difference in performance.
Manley recommends these specific exhaust valves for alcohol-fueled engines, as they hold up well in those demanding conditions. They feature a straight stem design, known as Race Master, which is one of the shapes Manley offers to match your engine's specific needs.
