Not sure why you need to skim the head if the gasket is gone. Surely a new gasket should be all it needs?
Anyway one of my Pan Euro heads is currently in KH Engineering at the back of where the Bulldog pub used to be. Don't be put off by the location 'cos they appear to be a very able bunch. I am having a broken exhaust stud spark eroded and was offered a skim when I dropped it off. They had a very new engine there waiting to be cut in half which is definitely not a job for the faint of heart....!
