Planning on adding some HP to your Apache? DON'T FORGET ABOUT YOUR CYLINDER HEADS!
We actually can offer one lucky member the rare opportunity of having their head upgrade shipped out TODAY! We hardly ever have the chance to build anything for our stock. So do not miss out on this opportunity!
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.
5 axis CNC machined
Fully assembled
Custom CNC valve job
Upgraded stainless steel intake & exhaust valves
Mopar guides, valve seals, retainers, locks
Upgraded valve springs
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.
Includes:
Upgraded rocker bar shafts
CNC rocker bar hold downs
8740 Chrome Moly hold down bolts
Shaft washers and shaft collars
Adjustable clamps for setting rocker position
4130 chromoly shafts offer increased wall thickness versus their OEM counterparts
Decreasing deflection and flex
Microfinished shafts feature low RA to reduce friction between rocker arm and rocker bar
DLC shaft coating provides ultimate in friction reduction and durability
