My question is do I need to use the Inj diffusers? Has anyone taken them out, and ran the inj without them? Reason i ask is because the injectors I have dont really sit on the diffusers the way they should. They dont seem to be the correct ones, as far as how it fits onto the diffuser. I bough the car like this with these injectors. When i was taking the motor apart, all the inj seals were ripped or pinched, and i'd rather not put it back with this current setup.

if you want the fuel properly atomized fuel then yes. if you want crappy gas milage and other random problems then no you dont.
