There is one large one on the back side as Mike states. The parts catalogue
that I have reads that there are 6 each 118686 gallery plugs, but it is
useless for determining their location, since there are two under the engine
mount casting and only one hole is shown. See AH12 in TRF's parts list. The
only one I didn't remove, PS1103, is called the plug, core, oil gallery,
front. Mike's advice is sound, and remove anything requiring a hex wrench.
Get new ones, they're 65 cents apiece.
As to the freeze plugs, a couple have cast iron rims behind them, so
drilling along the edge won't work. I punched all of them in the center
using a sharp steel tapered punch to create a hole large enough accomodate a
3/8" self-taping screw, and yanked them out with a crow-bar hooked under the
screw head.

Subject: Gallery plugs
Last winter when I rebuilt my engine I removed all soft plugs ( aka
expansion
plugs) and oil gallery plugs before taking the block to the machine shop. I
removed the soft plugs by drilling a hole in them and then using a slide
hammer. You must drill near the edge of the plug for this to work-if you
drill in
the center of the plug it will flex and not release from the block. As to
the
oil gallery plugs follow the trail of plugs from the front of the block
along
the left side just below what you could visualize as where the camshaft goes
through the engine. I am working from memory (dangerous) but I think there
are
five on the side and one on the back. Others with either better memory or
more
experience may correct or corroborate. I think it's best to remove
everything
you can so as to ensure all crud is eliminated. Clean is good.
Good luck on your rebuild
