Ordering the kit to finish a block, its a 400 SBC. I notice on Summit they offer Two different kits for the 350, etc. and the 400. Whats the difference? Is it because some 400's had 3 plugs on each side? Aside from that are they the same? Mine only has 2 plugs per side so should I just order a kit for the 350?

I would still order the 400 kit. If you screw up installing one of the plugs you'll still have a spare or two. ;)

The newer 350's use different sized cup plugs above the cam whereas the early 350's and all 400's use 1/2" cup plugs on all 3 positions.

They are the same, except the 400 has 2 more plugs.
