understanding a low oil pressure 360

As far as I know the "big mistakes" for oil plugs are the two up front where the lifter galleys terminate, the screw in one INSIDE the block back by the dist, and then the little tiny one up in above the oil pump. I too do not remember the dimension anymore. See if I can find it.
