So what is the best and safest way to remove the cylinder head exhaust studs and bolts or nuts ?    Probably they have very many years of rusting so soaking them in PB Blaster or Kroil is certainly going to be necessary.  I would guess driving on a socket of perhaps 1 size smaller than the nominal size so that there is less chance of slippage and rounding off of the nuts.      Should one dispense with that and use a dremel thin grinding wheel to carefully grind off one area of the nuts so that they can be broken off the studs without stud damage?    Cleaning off the threads remaining with the correct size thread die so that new nuts will fit nicely?        Once again I would like to hear the opinion of those who have successfully done this troublesome job.         Thanks,   Steve
