Slant 6 exhaust leak.

So if I stay with what I have, do I need to order a 2 or 2.25 inch gasket? I will make a note of that 2.25 head pipe, but for now I want it to run, so I'll be able to pull it in and out of the shop,

Manifold outlet is 2" and the headpipe is a pathetic 1-3/4" piece; make a note to get a 2-1/4" headpipe made when the time comes.

as I do the body sanding, outdoors.

I'd like to get all the parts and tools gathered and ready before I start disassembly.
