Also, I put the studded bolt in the second postion, but this puts the dipstick in the way of screwing on the nut that holds the battery cable. Is this pic an original? I think it makes more sense to put the stud in the front position like yours.
The pictures in the post that you quoted are of my engine. They show the stud in the front position, but I'm pretty sure a previous owner took the heads off, so I'm not sure that they put the stud back in the original spot or not. If the dipstick tube interferes with the stud in the second position, maybe the front position is the way to go.
I found another picture of a different car that also shows the stud in the front spot, but again, I don't know if it is original.
