93 octane
As far as ur cams give comp cams a call to verify if what u have will be doable for the power ur trying to make. The heads seems ok to me honestly. For a boosted application some want boost quickly while others want boost in the highs 6k rpm range. Thats how my setup is. I built my motor and all to support it so around town I see 3 to 7 psi. I didn't want a all out track car so that's why. I am pushing 14 psi putting down 612 601 tq thru a 4r70w in my 01 GT.
For your setup I can see even higher do to fuel setup u have. Now u need a tuner that can dial it all in.

Fuel system is optimum for that set-up . I would be looking for at least 60's or 80's for that size turbo and two 340 fuel pumps . Just my 2 cent
