Default Fuel injector question

I just can't seem to find the straight up answer so I figured id make another post. Im planning out a 900hp+ 408 ls1 240sx swap drag car. Ive been meticulously planning this out because I'm just that kinda person. Im at the fueling part of the build list and i cannot find a straight answer if 120lb injectors are totally plug and play. Can you just drop them in like the factory ones? It seems like theres some type of modification that needs to be done but I can't get a 100% answer. If I go 120-160lb injectors what ALL is needed? Thanks

Stock intake? Who's injectors? Stock intake with Holley injectors, I think the height is the only difference. FAST intake you have to grind the intake some to clear the large body Bosch style injector. Not sure if there are slim design 120lb or 160lb, just never seen any but those should drop right in to either other than height and of course plug size. There is also the o-ring issue. The FAST needs a larger one to fit the intake, that FAST sells.
