Head Skimming
How do you tell how much has already been taken off and if it can be done again.
Got no reason to think it would need skimming but was gunna get it done for good measure.

Minimum thickness between the upper and lower mating faces (where the gaskets go) of the head is 138.68mm.
Maximum deviation between bolt holes (laterally across head) is 0.02mm, and 0.08 mm maximum bow along centre line of cylinder head (hg face).
Max permissable bow along centre of rocker cover face (top) is 0.10 mm.
You need a flat edge and feeler gauge, or entrust the work to a tuner/engineer.
