The cylinder head has two drillings through the fins. The lower one, which is a straight shot in, is where the head stud is, with its round 10mm stud barrel nut - the things you tried to retorque/test and some confusion arose.
The second drilling is right above it, and is for the spark plug. The spark plug is not a straight shot. It angles up and to the rear some - that's the angle you have to set your spark plug wrench when R&Ring a plug on the right bank (up and forward on the left bank). If you pull the #1 plug and look in there (where you can stick your head), you will see the layout.
So my guess is that you have a fine photo of a head stud barrel nut.

Walt, I noticed that the photo got posted upside down but I couldn't tell the difference between the head stud hole and the plug hole without looking at it directly
I know it by feel, though - i go straight down the hole in the VC and angle it towards the back of the motor slightly.

I wish I had thought of that when I was working on it last week. I knew that once, but had totally forgotten it. The people in the SJ Wagoneer that stopped to offer help and follow me back to dinner suggested that (and produced some hose) and indeed it makes it easy-peasy.
Given the above re: grease and doing it safely in the car, and that taking the head off is going to be, I dunno, triple the work, I'm probably just going to drop the motor onto a furniture pallet and do it there.
How do I do a partial drop? That is, what do I remove and what do I not touch?
