You'll need to make a good seal where the EGR went into the manifold, 1-3/4" adjustable freeze plug does this well.
You need the upstream O2's. Do you have them disconnected so you don't burn 'em up? (open headers) You can leave the downstream O2's with sims plugged in, they ONLY keep the SES light from coming on, but that will probably come on anyway, since you don't have the front O2's plugged in.
