About this part

Product Details

These Manley Race Master exhaust valves are built with a 31mm diameter and a 4.587-inch overall length, specifically designed for Ford 4.6L engines. They are constructed from high-quality stainless steel, chosen for its durability under demanding conditions. The chrome stems and hard tips add to their longevity, helping them resist wear over time.

The valves feature swirl-polished under-head areas and fully machined combustion faces. This design helps optimize airflow into the cylinder, which can contribute to better combustion efficiency. Manley offers these in a Race Master (straight stem) shape, which is a solid option for engines running up to 8000 RPM. They are also recommended for use in alcohol-fueled engines, where they offer reliable performance.

This set includes eight exhaust valves, making them a good choice for a complete engine rebuild or upgrade. If you're working on a performance Ford 4.6L, these valves are a well-built component to consider.
