 I have had reason to take the head off my engine and although I have had no problems i that area I was pondering whether it would be worthwhile to have the head skimmed before refitting. I have two reasons, both of which may or may not be a good idea and happy to be told so. Firstly to head of any problems of a warped head that may be creeping in, and secondly as it would in theory increase the compression would is it a bonafide way of extracting (a little bit) more performance?  Questions -  how much can you take off the head before the valves and pistons start colliding? I would think this is in ratio to the amount of standout of the piston above the liners but I cannot find any figures to work from. I have looked all over the head and I cannot see any marks that would indicate it has been skimed before - how could I tell, are there any measurments that can be taken? Any advice gladly received. I really appreciate your site for the specialist knowledge available as over hear in the UK we seem to concetrate on polishing

Thanks
