They are down low, on the sides of the block, just above the oil pan. They are a brass plug that screw into a hole drilled into the block, and they have an allen head 6-sided hole bored into them. Sorry, no pics; that was recollection from when I pulled them out years ago. They are definitely not easy to get to. Of the 4 on my twin engine 496HOs, I could only get to 3 of them. The center stringer was in the way of one of the inboard plugs.
