Doug,
At this point, all of the 102 complete gasket kits on the market are coming from the same manufacturer. I don't recall the name, but the gaskets are OK, if not wonderful. Several of them are different than the original, and some won't fit all that well. The price is better than it used to be, though.
The exception to this might be from AFRA. Of course, they are woeful at marketing, but I bought a complete gasket kit of theirs several years ago, and all of the gaskets contained were first rate. The kit came in a big cardboard box, and it appeared that they had taken time to find and assemble OEM gaskets for everything. It cost more than the ones from OKP, etc, but if I need another full gasket set, that's who I'd talk to first.
There is another company, Dichtungen Schwarz, that makes head gaskets. Very, very high quality. Fairly expensive. PITA to do business with. Probably the best head gasket I've ever bought for a 102.
Lastly, there have been a few guys on the BB that have undertaken to have one or the other difficult gaskets made. Specifically, the copper exhaust triangle and head-to-pipe gaskets (all of these are different from the later all-aluminum engines). Another fellow had the rear bell housing plate to crankcase gaskets made. The ones from OKP et al are just a thin paper unit that's not shaped right. The original is a fairly thick gasket shaped sort of like a squished "H". You might be able to find them by searching the BB, and see if they have any left.
Good luck
