Once i blow up this magnum motor or get my times I want on the race tune, I will be starting my Gen III hemi collecting. I want to go 6.4 block and apache heads with a BIG! turbo or maybe twins



Im not sure you can put enough valve spring on Apache heads to control the valves under alot of boost. The guide is held in place by aluminum boss on top of the port where on a 6.1 head the aluminum boss is in the port. The thitek head might be the best route for a serious effort

Gen 3 power 6.22@110, 9.85@135
