Cylinder Head Tolerance Question
Right. My original heads went in for a check over on Thursday and the findings are:
One of them has a minus 2 thou (0.0508 mm) area smack in the middle of the head and bang in between both combustion chambers.
The other has a minus 2 thou ( 0.0508 mm) area alongside both combustion chambers between the chambers and the edge of the head below exhaust ports.
Question is: Is this within recommended tolerances or will they need to be skimmed ?
We will be fitting Victor Reinz tri layered quality head gaskets.

0.002" is the top end of the tolerance so a light skim would clean them up back to parallel.
Make sure they skim both heads equally and the maximum regrind limit on standard height heads is 0.012".
