Hi Dee,
When I rebuilt the engine for my '70 MkIII Spit I had the head surfaced. Based
on the machine shops advice I did not use any type of compound with the gasket,
however mine leaks an ever so small amount of oil at the left rear corner.
This leads me to believe that I should have used a gasket compound. Oh BTW the
deck of the block was surfaced too. I'm not at all worried about the leak, at
least I know oil is making it that far :-).
Good Luck
