Manley 12-14 Chrysler Hemi 6.4L 2.180in Head Dia Race Master Intake Race Flo Valves (Set of 8)

When you're rebuilding the top end of your Chrysler Hemi 6.4L, you get a set of eight Manley Race Master intake valves. These are built for engines that see some serious action, especially if you're into bracket racing, drag racing, or oval track use, and they're designed to handle up to 8000 RPM.

You'll find these valves are made from stainless steel, which is a solid choice for durability. They also feature chrome stems and hard tips, adding to their lifespan and resistance to wear. The under-head areas are swirl polished and the combustion faces are fully machined. This design helps optimize airflow into the cylinder and can contribute to better combustion efficiency. Manley offers these in a Race Master (straight stem) or Race Flo shape, and these particular ones are the Race Master type with a 2.180-inch head diameter.

These valves are also recommended for use in alcohol-fueled engines, particularly for the exhaust side, where they can offer reliable performance under demanding conditions. If you're pushing your Hemi hard, these are a well-built option to consider for your build.
