Default LS2 Injectors on an LS3

Hey guys. I found some 60lb injectors for a good price but they are LS2 injectors and I have a 2008 with LS3.
I've searched and found tons of results for going ls3 to ls2, but not any going this way.
Will they fit my car without any modifications or very minor ones?

You'll have to use spacers to make the fuel rail higher. I've done it before as my car is an LS2 car and swapped to ls3 heads/intake and kept the same 1000cc injectors.. I just can't remember what the dimension was for the spacers.

I believe ls3 and ls7 injectors are the same. Might help you to broaden your search
