Wrong shape on the heads. The LS2 is a cathedral shape the LS3 is rectangular.

Ooops, my bad. I was referring to the E-Force unit, not the one you have. I'll be quiet now!

You will need different injectors. LS3 injectors are short, LS2 are tall. There will also be some other small items depending on what type of kit. Call either ECS, A&A, or whoever makes the kit so that you know you get all the parts and your build is not stopped. 
EDIT, saw that you edited your post too. Call A&A, they should get you squared away.

I bought a used recondictioned Vortec with A&A bracket.
It came off a C6Z and I had it installed on my LS2 w/o any problems.
3.8 pulley putting out 11.psi boost.
I had a 50/50 meth kit installed also..engine is all stock, no cam, no heads and no long tube headers...RWHP is 566/ RWTQ is 506
Get one and enjoy it.
