Ahh....my bad, i didnt realize you were running a FI 5.0 engine. With all the power adders you will possibly need a new fuel pump and bigger injectors, but im no FI wiz.....but you can still port match the intake runners to the heads and get 10 free horsepower. A set of AFR 165 heads, maybe and E303 cam (you may already have in the car), port match job, retune of the computer to match the new components would really liven things up for you.
The simplest way to think of an engine is like an air pump....the easier it can get air in and through the engine and out the tailpipe the more power its going to make. Porting and polishing of the original heads enlarges the intake runners, allowing more air to get through the engine, then polishing the exhaust runners allows the gasses to escape easier, thats where most of your HP is made in an engine...combine that with a healthy compression ratio (9.5:1) and you will have a good combo.

X2, really the focus is behind the intake valve on a blower deal. If your thinking of changing your cam I would always go the custom route for a few bucks more. Someone like Ed Curtis from FTI would be the way I go. It is the way I went on my build and I'm ecstatic with it.
