95 SC combo ?

95 SC (automatic) cracked head replacement has morphed into complete rebuild and upgrade. List below are parts I have. What size injectors would work best (42 or 60), is 85mm TB worth the price difference of the 75mm TB for my combo? I also plan on getting QH from Dave once everything is together and car running.

Existing parts

MPII inlet & Supercharger
Stock throttle body & filter box (silencer removed).
Stock (IC)
Stock injectors
Stock manifolds (ported)
Scorpion roller rockers
Forged Wiseco pistons
Stock rods w/arp bolts
Adjustable fuel regulator
76mm pro- M MAF setup for 24lb cobra injectors

New parts I have acquired

Heads with 1.84/1.5 Chevy vortex valves optimized chambers, seats & bowls by P&M performance
Comp cams beehive springs kit for cam listed
Comp cam Grind#265HR115
Main cap stud kit
Aeromotive 340 fuel pump
Screamin demon coil
Livewire plug wires
MLS head gaskets
SCP 3.5 fresh air inlet system

The 85mm TB is definitely worth it. I would also ditch the Pro-M MAF and get either a 90mm lightning MAF, or a slot MAF and tune for it. As far as injectors go, might as well get the 60s. The 42s would work, but they won't give you any headroom if you want to make any more power, and once tuned properly, there is no downside to going with the larger injectors.

I would also go with the #60s once you start modifications you get the bug and it snow balls into wanting more. Next thing to strongly consider is a way to cool the intake temps.
