dude im sure you'll be good with 750 primaries. maybe even 550's. my buddy was running a T66 precision turbo with cleaned ports on his fd with his stock primaries and 1300 secondaries. so you really dont have to go too big with primaries. especially for a stock port engine.

gsl-se injectors are 680cc. You can use them on the 720 primary settings, but your mixtures will be 6% leaner at idle and under vacuum/low RPM boost. I would suggest 720cc or 750cc to prevent a ton of tuning the vacuum cells. It's not easy to datalog those areas of the map.
720/1000 may be a little short for ~350 whp. Don't increase primary size; increase secondaries to something like 1200c if you're worried about it. That's about the largest injector controllable on an Rtek 2.x.
