Well my first question to you would be what are your future plans? Because depending on whether boost is in the works or not depends on what cam you'll want. Also (and no offense) have you looked up the entire price of a cams and springs? I know it blew me away when I checked.
My next suggestion would be to get supporting mods while you do the PI swap. Headers, throttle body, plenum, exhaust, the whole works. I don't know what your budget is or if you're going to take it to a shop but you'd be surprised what the thing can do without an aggressive cam. I had all of the bolt ons I mentioned with the full PI swap no tune and I made 300 to the wheels! I'm not trying to discourage you from what you had planned just letting you know the other options out there
