I expect these are original.

Ouch....
Was it the end of a production year or something where they ran out of
the proper bolts? I got 'lucky' that way on my CJ7. They ran out of
stock AMC rear ends so they put a Dana 44 in...
The only time I normally see the studs on top of the nut like that is
when a bracket or wire needs to be bolted on after the part is assembled
or as I mentioned, someone screwed up and lost parts.
Is there any pattern to them or are they just random? Maybe they are to
position the engine in an assembly jig or something? Are they pointy
ends, slot ends, hex ends or just flat?

various fasteners go on them for auto trans lines and o2 sensor wires

Woo hoo.. a correct answer. :)

At the bottom you see the O2 sensor connector.
That's pushed on one of those studs that hang down from
the oil pan. Rather than make many different setups
for each production vehicle they simply put studs where
they would be needed no matter what vehicle the engine
will be installed in.
