Manley Ford 4.6L Modular V8 Exhaust Valve Kit - 34.00mm Head Dia. 4.650in O/A Length, 0.2740in Stem

When you're rebuilding the top end of your 1996-1998 Ford Mustang's 4.6L Modular V8, the exhaust valves are critical for getting that air out efficiently. These Manley Race Series exhaust valves are built from XH-426 stainless steel, a well-known material for handling the heat and stress inside an engine. The 34.00mm head diameter and 4.650-inch overall length are specific dimensions to ensure they work correctly within the cylinder head for your Mustang.

Manley takes these stainless steel valves a step further with a swirl polished finish under the head area and a fully machined combustion face. This design helps smooth out airflow as the exhaust gases exit the cylinder, which can contribute to better overall engine performance. They also feature chrome stems and hard tips, adding durability and wear resistance where it counts, especially important for engines that see a lot of use or operate at higher RPMs.

These valves are also a recommended choice for alcohol-fueled engines, indicating their robust construction and ability to handle demanding conditions. If you're looking for a solid option for your Mustang's engine rebuild, these Manley valves offer a well-built solution with features aimed at improving airflow and longevity.
