should a head always be skimmed when doing a head gasket? ive done lots of hgs befor and never had a skim. my old metro did over 150k on the factory gasket which i changed and then did about another 100k before the back end rusted beyond repair and i had sto scrap it. if its badly worped then yes i can understand skimming. but without a thicker gasket it will up the cr slightly and retard the timing also.

The old A series engines are cast iron heads and you can often get away without. The Fiat heads are alloy and mark / score easily when the gaskets fail so it's worthwhile having it done.

I would (and did). For the sake of the £30 it cost me it gave the peace of mind that I wouldn't be pulling it all apart again in a few months.
