Default Injector size?

I'm Putting together an engine and don't know which size injectors to buy. I've got a 6.0 with L92 heads, MS4 cam, and a GMPP intake. Can someone help?

how much power do you think it will make. A 6.0L makes what stock? 350~360?
So lets call it 450RWHP to be on the safe side as you have some mods, I would grab some 36# injectors or even 42# and forget it.

with the 42# you could drop them in and tune it and have plenty of an injector left over for more mods. This would also have great driveability and would be easy to tune the 42#.

this setup is naturally aspirated right? (meaning no boost)

Is That 42# at 3 bar or at 4 bar fuel pressure? It's naturally aspirated.
