Porting and polishing can allow for better gains, as it helps with flow characteristics. I wouldn't just do the intake side of the house though, I'd do the head as a whole. Also, why port the throttle body? Just go with a different TB and get a JWT or Calum ECU. JWT has a nitrous program, IIRC. Doesn't matter what injector size you go, they're still going to flow at the stock FPR settings, unless you get an AFPR and a fuel pump that will support higher flow rates.

that will be about 12.5:1 compression or so, maybe 12.8:1.

with those cams, i dont think i'd mill the head, your comp may be too high and you may have detonation issues.

Why not have someone build you a head, who knows the entire situation your motor is currently able to withstand? You can spend 3g's getting a head to flow and it's worth it, (When it doesn't blow up, cuz of mismatched parts).
