The way around 'good and bad' with porting is to demand a before/after flowbench sheet for YOUR head from the porter of your choice. That leaves little to speculation, and head porting at this power level can be worth a substantial power increase (think Honda B-series numbers).
As for the BR '280/280' cams, I assume you are referring to the new cams? Be certain.

Is this a Precision Turbo, T67 Turbo with p-trim & t-4 housing? or, is it the same turbo, with a t3 housing machined to fit the p-trim wheel? I think this combination is what is called the gt37r.

i wonder why
awesome numbers, and to think they could be improved with some better cams is even better!
Flex Fuel make me happy in pants. 9,000 RPM 
even better congrats.

Jasil is correct.
If one looks at the specs for those cams:
http://www.briancrower.com/makes/mit...g63_evo8.shtml
There are two things that immediately come to attention. The first is the fact that these cams only give 218/216 deg of duration at 0.050", which is not ideally suited for high rpm power. Likewise, I see "106" indicated, which probably refers to LC (for both). !

For example, to my knowledge there is no way to compare durations of cam A measured at .050 vs cam B at 1mm. So you can't guess that a Jun 272 that has an effective duration of 235* at 1mm likely has more RPM potential than a BC 280 which 218* at .050" My current understanding is that the only way to compare would be to have each cam set and measure them for yourself.
Is someone aware of a domestic grind with more RPM potential than the BC280s?

We have quite a bit of meth in there so the DC were at 71% peak.
Plans for the car in order are
-Boost leak check to 40psi
-cam gears set like Ted said than play with them some on the Dyno
-C16 tune with and with out meth
-Cams
If the head ever needs to come off than port work to.

Paul boost is not allways the key
We could have done 40psi if we wanted but no need if it does not make any more power. When we went from 35-37psi and only picked up 7hp there is no reason to push it harder on boost. We picked up almost 30hp going from 33-35psi.
The turbo is a T4 P trim exhaust. Talking with AMS it looks like we should get over 700hp.
