Going together. I got the head on and found two broken valve stem seals, so I'm going to use the compressed air method for holding the valve while I replace the seals.
Just need to get the rear main seal on, then I can put the oil pan on and start dressing the outside of the block. I need the stem seals and freeze plugs, then it can be buttoned up and installed in the car. The problem with having the head and manifolds on when it goes in is that I have to remove the hood. Oh well. small price to pay for making things easier overall.
