Well, so glad so many people have made use out of this how too that I did a couple of years ago, if it just saved one motorist from scrapping his car, its win win.
As to the above statement, there are of course various points of view on this, however mine is that the head should NEVER be skimmed for the sake of it, as it has a heat proof coating on which would be removed if this action is taken and of course there is only a finite amount of times you can actually skim it before the clearances have been changed catastrophically meaning of course a new head is needed. It's fair to say if you use the older style gaskets, they can fail quite quickly after the refit (I recently purchased two that had gaps in the beading!) meaning if I skimmed it, fitted it and had to skim it again because of the faulty gasket, you could be out of tolerance and need a new head... seems pretty pointless for the sake of it!
You only need to skim a head if it has warped, usually due to over heating, I do think it is a pointless waste of money and totally unnecessary in most cases. i.e. just because you have head gasket failure, doesn't mean the head has over heated and any engineer worth his salt can check if the head is warped.
The key is if you do this job yourself, once the head is off, go and check to make sure the head is ok, if you can afford, get it pressure tested and checked to ensure its not warped or heavily pitted If it is, then and only then get it skimmed.
Still, all this is my own opinion and I don't recognise the need for pointless work being carried out, especially at a time when most people cant afford it.
Thanks again folks
