Manley Ford 429 Boss Exhaust Valve Kit - 1.900in Head Dia. 5.650in O/A Length, 0.3715in Stem

Manley Performance is well-known for making strong internal engine components, especially for racing applications. This exhaust valve kit is built for Ford 429 Boss engines, designed to handle the stress of performance use.

These valves are made from stainless steel, which helps them stand up to the heat and pressure inside the cylinder. The under-head areas are swirl polished and the combustion faces are fully machined. This design work helps improve how air moves through the cylinder, making combustion more efficient. They also feature chrome stems and hard tips to resist wear, giving them a longer service life. If you're building an engine that runs on alcohol, these are a recommended choice for exhaust valves because they hold up well in those conditions.

This kit includes exhaust valves with a 1.900-inch head diameter and a 5.650-inch overall length, featuring a 0.3715-inch stem.
