About this part

Product Details

If you're rebuilding the top end of your 2011 and up Chrysler or Dodge with a 6.4L Hemi, these Manley Race Flo intake valves are a solid option. They're built from stainless steel, which is a strong material that holds up well over time, especially in performance applications. The stems are chromed and the tips are hardened, adding extra wear resistance where it counts during operation.

Manley also put a lot of thought into optimizing airflow. The under-head areas are swirl polished, and the combustion faces are fully machined. This helps the engine breathe better and burn fuel more efficiently. These are the Race Flo shape, which is designed for specific racing engine setups, and they're even recommended for exhaust valves in alcohol-fueled engines, showing how well they handle tough conditions.
