Doorman,
You have not to far from you T-Man, and a little south you have Cycle Rama, but your 2500 dollars isnt going to cover much if you send out the heads for their porting or cams.
Not sure I would go with a gear drive in an 07 due to the crank run outs, unless your going to dig deeper into your pocket.
I agree with HD-Dude and would suggest calling one of the guys above or cross the country to Dan Baisley or Dave Mackey those are 4 good named people that will do the job right. The rest is up to you and your wallet. Most of the better porters are going to be from 900 - 1500 dollars or more for the porting etc. These guys will get you an entire package that will run along with their heads that should give you what you are looking for.
If your not going to dig deeper, the suggestion would be new lifters, hd 110 pistons 10.5 to 1, horsepower inc 55 or 58 throttlebody in prep for headwork later, HD 251 cam and adjustable pushrods / tubes (S&S). Then you have labor, SERT, Tune and pipes.
