What material are these valves made from?

These Manley Race Master valves are made from stainless steel for both intake and exhaust. The stems are chrome-plated with hard tips for added durability and wear resistance.

Are these valves suitable for all types of engines?

These valves are specifically designed for racing applications, particularly for engines operating under 8000 RPM. They are also recommended for exhaust valves in alcohol engines due to their robust construction.

What is the benefit of swirl polishing and machining?

The swirl polished under-head areas and fully machined combustion faces are designed to improve airflow into the cylinder and enhance combustion efficiency. This helps your engine perform at its best.

About this part

Product Details

These Manley Race Master valves are built with a 32mm head diameter and a 5.96mm stem, measuring 4.274 inches in length. They are constructed from stainless steel, which is a solid choice for handling the heat and stress inside your engine. The stems are chromed and feature hard tips, adding to their wear resistance and making them last longer through many cycles.

The under-head areas are swirl polished to help smooth out airflow, and the combustion faces are fully machined. This attention to detail helps optimize how air and fuel move through the engine and how efficiently combustion happens. Manley recommends these for alcohol-fueled engines, especially for exhaust valves, where they can handle the demanding conditions reliably. They come in a set of 8, ready for your Coyote 5.0L DOHC build.
