About this part

Product Details

Manley Performance is well-known for making strong internal engine components for racing applications. These Race Master intake valves are a great example, designed for Ford 4.6L and 5.4L SOHC engines that see a lot of use, especially those running up to 8000 RPM. If you're rebuilding the top end of one of these Ford modular engines for performance, these valves are built to handle the extra stress.

These intake valves are made from stainless steel, which is a solid choice for durability. They feature chrome-plated stems and hard tips to resist wear over time, especially with frequent use. The under-head area is swirl-polished to help smooth out airflow into the cylinder, and the combustion face is fully machined for better efficiency. The Race Master design has a straight stem, which is a common choice for many performance builds.

This set includes eight intake valves, enough for a V8 engine. They are also recommended for use in alcohol-fueled engines, which can be tougher on components. If you're looking for well-built valves to support your performance Ford engine, these are a popular option.
