42s should be plenty big, but I don't see 48s shouldn't be a problem. I've got 48s on mine without any issues.

Yeah, don't even waste you time/money with 36s.
I'd also upgrade the fuel pump, if you haven't already.
I got my injectors here:

You should be fine they will just run at a lower duty cycle. We always suggest running a bosch racing ls1 series injector.

unless you plan on adding some big power to that NA engine 48s are a waste unless they are priced right.

42# would be perfect. I'm willing to bet 58% duty cycle
