I'm in the same boat with you, got a lovely Holdsworth path racer whose paintjob is faded but lovely, but the headtube need replacing as it's too worn out and may need new lug, also the fork is slighty bent by a millimetre, but decided to get it repair and clearcoat it, keeping the paintjob despite the unpainted headtube and lug.
sometime I feel it's worth keeping the original paintjob, unless it's really bad and the best thing to do is to get it restored to it's original paintjob.
