About this part

Product Details

Manley Performance is well-known for making strong internal engine components for racing applications. These Race Master exhaust valves are a great example, built specifically for Ford 4.6L and 5.4L DOHC 4-valve engines. If you're rebuilding the top end of one of these popular Ford modular engines, especially for racing under 8000 RPM, these valves are designed to handle the stress.

They're made from stainless steel, which is a solid choice for durability, and feature chrome stems and hard tips to resist wear over time. The under-head area is swirl polished to help smooth airflow, and the combustion faces are fully machined. This attention to detail helps optimize how air and fuel move through the cylinder, which is important for getting the most out of your engine. Manley also notes these are recommended for alcohol-fueled engines, which can be a demanding environment for exhaust valves.

This set includes eight exhaust valves, specifically the Race Master straight stem style. When you're putting an engine together for serious use, choosing well-built internal parts like these from a reputable brand like Manley makes a big difference in reliability and performance.
