That turbo has too small a turbine. You're adding GT2 Evo cams in a turbo'd engine that will choke you with back pressure on the top end(not good). If you insist on the GTX30776R turbo, go with shorter duration cams.
I also think you may be undersizing your headers with the FabSpeed units. Anyone can chime in here, but with the size of those primaries, they may be too small for the 3.2 exhaust ports? I love the 3.2 engines. Those heads flow really well. Just think there may be issues with port mismatch to primaries.
