Manley Chrysler 361 Exhaust Valve Kit - 1.740in Head Dia. 4.908in O/A Length, 0.3720in Stem

Starting with a 1.740-inch head diameter and a 4.908-inch overall length, these Manley Race Series exhaust valves are built for serious performance. The 0.3720-inch stem diameter ensures a solid fit in your Chrysler 361 engine. These valves are constructed from high-quality stainless steel, giving you a well-built component that can handle the heat and stress of demanding engine operation, especially if you're running alcohol fuels, as these are specifically recommended for that application.

Beyond the robust stainless steel build, Manley has added chrome stems and hard tips to further improve wear resistance and longevity. The under-head areas are swirl polished, and the combustion faces are fully machined. This attention to detail helps optimize airflow into the combustion chamber and can contribute to better combustion efficiency. You can choose between Race Master (straight stem) and Race Flo shapes to best match your engine's specific needs and airflow characteristics.
