I've never heard of "blowing" an oil ring. I'd suspect something related
to your fiddling with the carbs. Especially because black smoke
indicates a very rich mixture. If you were burning oil, it would be
blue. Plugs can be wet from gas.

I don't mean to insult you, but you may not have the basic level of
knowledge to do this job just yet. At the very least, you need to get
some books and do some reading. Std = standard. The others are
oversizes to fit cylinders that have been bored out to diameters 20, 30,
and 40 thousandths of an inch oversize.

Yes, but read up on it. The cylinders may have been bored to an oversize
already. Even if they have not, you need to ensure that the cylinders are
round and not tapered beyond reasonable limits. If that does not make
sense, do some reading.

This car does not have them, and they are only in order if one or more
cylinders is worn or damaged in such a way that it cannot be reclaimed
by a standard rebore.
Once again, though, I think you are jumping to conclusions about the
cause of your problem. You may be right, but eliminate less expensive
