It will work but you won't be able to run much boost with that setup

Everything looks fine except obviously the headers, injectors being too small and I recommend running a spec'd turbo cam.

What size injectors should I get and what turbo cam will work " do you know of any specific kind of that you would recommend "and I'd like to get a cam that sounds like mine basically I don't want to sound stock I want to hear a lump if that's possible I also plan on using 317 heads and ls9 head gaskets with arp head studs

maybe consider a better intake too. just an idea since youre looking to make some serious power.

Stock LS1/2/6 intake will be more then enough for 700 rwhp.

like everyone said above, you will need atleast 80lb injectors. i just put down 746rwhp on my ls1 5.7 with a torquer v2 cam on a 112lsa and an on3 performance 78/75 turbo. not sure what your compression is with those heads but that could be your limiting factor if youre running pump gas and trying to make 700hp.
