I need to know the gap and what kind of plugs I need to use with a 6AL on a Small Block Chevy 350 street engine

I would recommend running a 0.040 plug gap with the MSD 6AL Ignition, PN 6420. As for the spark plugs, I suggest that you run one step colder than the recommended stock replacement plug.
