What material is this exhaust valve made from?

This Manley exhaust valve is constructed from XH-426 stainless steel. This material is chosen for its durability and ability to withstand the high temperatures and stresses found in performance engines.

What is the purpose of the chrome stem and hard tip?

The chrome-plated stem helps reduce friction and wear as the valve moves within its guide. The hardened tip is designed to withstand the repeated impact from the valve train components, increasing the valve's overall lifespan.

Is this valve suitable for all types of engines?

This is a Race Series valve, recommended for engines operating under 8000 RPM, commonly found in bracket, drag, and oval track racing. It is specifically recommended for exhaust valve use in alcohol engines due to its robust construction.

About this part

Product Details

You're getting one Manley Race Master exhaust valve, designed for Ford 5.0L engines. This valve is built from stainless steel, specifically the XH-426 alloy, which is known for holding up well under heat and stress. It's a straight stem design, part of Manley's Race Series, intended for engines that run up to 8000 RPM, making it a solid choice for bracket, drag, and oval track racing applications.

The stem on this valve is chrome-plated for better wear resistance, and the tip is hardened to handle the impact of valve train operation. Manley also swirl polishes the area under the head to help improve airflow, and the combustion face is fully machined for efficiency. If you're running an alcohol-based fuel in your engine, this valve is specifically recommended for exhaust use because of its robust construction and ability to perform reliably in those demanding conditions.
