H/C packages usually call for a tad bit bigger injectors. 30-42# in most cases.

38's to 42's will work for you. My 42's are a bit over what I needed for my 227/224. If you go a bit bigger, but not too much, then you'll have some future headroom.

Yeah, and even that is too big for just a cam.
I would get the SVO 30# injectors. They are actually rated at about 36#'s in an LS1.

The stockers might be able to handle it. When it is tuned check the duty cycle on them. Mine are only at 89% @ WOT with an F13

agreed. I believe the 28# can take most H/C's. But its a wise idea to go with some 30#ers.
