About this part

Product Details

Starting with a 1.508-inch head diameter, this Manley Race Master Series intake valve is built for the Ford GT350's Voodoo 5.2L engine. These valves are constructed from stainless steel, which helps them stand up to the heat and stress of high-performance operation, especially in engines running under 8000 RPM. The stems are chrome-plated for better wear resistance, and the under-head areas are swirl polished to help improve airflow into the combustion chamber.

The Race Master series features a straight stem design, and this particular valve has a .2355-inch stem diameter and an overall length of 4.780 inches. It also includes a 0.100-inch backcut at a 30-degree angle, which can help optimize airflow and valve seating. These are a solid option if you're rebuilding the top end of your Voodoo engine and need reliable intake valves.
