Difference in Oil pan gaskets

i want to say the move from the multi-pokey seal to the lip seal with just two (bigger) nubs was about 72(?)

i've done every which way on them darn things over the years: cut the nubs off the early ones, enlarged the holes for the later ones, drilled the pan for the early ones, etc. etc. etc.

i like to run the correct one for the pan. or if you're in a jam, and don't want to wait you can just run a fat bead of rightstuff™
