The baking solution was what was recommended for the S54 vs. resutface. If you're not racing the car I would have no problem taking off that 0.3mm to match the thicker gasket.

If it was within 1 mil of spec flatness I'd probably "just send it".

A 10mm 10.9 bolt yields at about 9000# so about 125,000# holding the head down will definitely remove some of that non flat. Just a thought.
