some headsets cups are wider in diameter then the rest...in order to get in the frame you have to ream the headtube...if you dont the tube will crack.....so maybe the frame originaly had headset this size or the person who was preping the frame reamed the headtube too much...........solution 1: try the shim as you said......wouldnt recommend.....couple of my friends in warsaw done that...i wouldn't
solution II : try to use some kind of glue to glue them in...no idea which type or where to get..i wouldnt
solution III: go into a shop ask for thier whole range of headsets and see which one fits........had the same problem....fort frame M part headset glued in....installation/removal by bare hands:-)...not safe i guess......i tried chris king.........behold......perfect fit...maybe even need a bit of facing...
so there ......i would say go to brixton cycles...best bike shop ever......theyll sort you out....
