Manley Ford Racing Cylinder Head 4.6L & 5.4L SOHC 36.0mm Race Master Exhaust Valves *Set of 8*

Manley Performance is known for making strong engine components for racing applications. If you're rebuilding the top end of your 1996-2004 Ford Mustang's 4.6L or 5.4L SOHC engine, these Manley Race Master exhaust valves are a solid option. They are designed to handle the demands of engines running up to 8000 RPM, making them suitable for bracket, drag, and oval track use.

These exhaust valves are made from stainless steel, which offers good durability. They also feature chrome-plated stems and hardened tips to resist wear over time. The under-head areas are swirl-polished and the combustion faces are machined to help optimize airflow into the cylinder, which can improve combustion efficiency. Manley offers these in a Race Master straight stem design, which is what you're looking at here, and also a Race Flo shape. These are also recommended for use in alcohol-fueled engines.

This set includes eight exhaust valves, enough for a pair of cylinder heads. They are a direct fit for the specified Mustang models and are a well-built choice for performance engine builds.
