Manley Ford 429 Exhaust Valve Kit - 1.880in Head Dia. 5.170in O/A Length, 0.3415in Stem

Manley Performance is well-known for making strong engine components for racing applications. This exhaust valve kit is built for Ford 429 engines, designed to handle the stress of racing up to 8000 RPM. If you're rebuilding the top end of a performance Ford 429, these valves are a solid choice for getting the most out of your engine.

These exhaust valves are made from stainless steel, which gives them good durability. They also have chrome-plated stems and hard tips to help them last longer and resist wear, especially important in high-stress environments. The under-head area is swirl polished and the combustion face is fully machined. This design helps improve airflow into the cylinder and can make combustion more efficient. They are also recommended for use in alcohol-fueled engines, which can be tougher on exhaust components.
