I would get 42# injectors and call it a day. You will have more than enough injector for your set up. Plus if later down the road you a bigger cam, change the heads of go with a FAST intake you are already covered

my moto: Do it once, Do it right

You would do just fine with #36 injectors,but if you plan on some changes later you might
get #42 to be safe.
