90Notch, thats my combo now, stock motor, Cobra intake and valves in untouched heads. It runs pretty hard, and Im sure a set of TFS heads would make it run a bunch harder, but for the $1000 they cost, I think the E7s can run extremely close! Its all in what you personally want though.
As far as the cam, I am no guru, I have only ever had a stocker and a B cam, and my only word of advise is to talk to a cam guy, and have one ground for what you want. Custom cams are much better than off the shelf, and although cost more, its worth it in the end.
