Really depends on what your definition of the "Whole Setup" is. For just the heads, cam, and intake...you could get those 3 itmes for about $2200. Of course, that'll get you nowhere without all the supporting items such as Roller Rockers, Throttle Body, MAF, Injectors, Timing Chain, Balancer, Bolts/Hardware, Gaskets, Gaskets, Gaskets, and depending on how modded you already are...you'll need a nice exhaust system to complement it all. Plus there's always a few hundred bucks in extras that seem to pop up.
I think you could be looking at anywhere from $2500-$4500.
