During a head gasket replacement, is it always necessary to have the head skimmed ?
The head on my cav was skimmed once before by the previous owner but i don't know by how much.

I've been told that it's always worth getting a skim when you have the head off. It usually only costs £20, they don't take off enough to cause any major effect to the comp ratio, and it will prevent any probs from any slight warps.

At least get it checked a good company will only skim if it needs it and if there is enough metal to do so.

Its not always the case due to the history/condition of the head.
