Whoa! they are not two different bolts. Well yes and no. The oil comes up on the driver's side, into the second from the front pedestal, and on the passenger side,it's second from the rear pedestal. But as far as the heads are concerned, the oil comes up through the second from the left pedestal, as you are bending over the fender.
A similar way to remember the notch orientation, for me, has always been, down and to the left, as you are leaning over the fender.
