Powerstorm Chrysler 6.4L Hemi Pro Series Heads
Our development process is what ensures a very high end product that offers better performance across the board. In combination with the increased flow, the heads are then outfitted with Livernois own proprietary custom components. Custom valves, springs, retainers and hardware are used to create a cylinder head combination that's built for ultimate performance and durability.
These head packages are built around Livernois years of racing experience and combine all the knowledge of our extensive development background as well. This is how we're able to offer cylinder head packages that are unmatched in their performance.

The upgrading doesn't stop there! Something that we all know is a shortcoming of the 6.4L head is valvetrain stability. This is what led us to developing our Late Model Hemi Rocker Bar Shaft Kit!
The Late model Hemi engine is a solid performer that responds well to adding an improved camsahft, and other supporting modifications. With these upgrades though, many Hemi owners notice increased issues with valvetrain related items. To help improve the valvetrain stability we have released our new complete rocker bar system. This system is a great bolt on upgrade over the stock rocker bar system and offers increased durability and reduces friction between the rocker arm and the shaft. For any serious upgrade with camshafts and higher pressure springs this kit is a must have to keep the valvetrain stable in your high performance Hemi engine.
