I'm stacking parts now for something similar on my 2007 Charger. I have a set of Eagles with new springs, valves, guides and valve job ready to go. Also have SRT shorties and cat delete pipes. Picked up the cam yesterday. Still need lifters, Cometic head gaskets, timing chain, oil pump and measure for pushrods when the new heads go on. I also have a 392 manifold that I may use. I am using a Diablo tuner. Already have the rear cats and EGR deleted.
