I texted youYes, the deck on the drivers side was resurfaced but I don't know by how much. I can't imagine it being more than 0.010 or so. Putting the front cover on before the head should eliminate any variance created by resurfacing the deck. The head gasket will compress by far more than the skim cut on the deck.
Interesting side note: I have a record of all the thrust washer sizes on both sides. It will be interesting to see if the thrust washer sizes on the drivers side need to be adjusted to bring the drivers side valve clearance alignment to nominal.
