I think what Arc was getting at is that is current head is at it's max marker and he wants to work out what the compression ratio will be.. 
Do you know if the head has been skimmed before?
But my experience says that you can skim the 8v head further than the max skim markers :devil:
I don't, i was going to ask this, is there any way to tell? i.e. any markings, measurements i can take?
Thanks again!

i suppose a way would be measuring from the cam cover face to the head face, accurately and then doing the same on non-skimmed head.
