The proper way to do it is to add new brazing material to the inside of the head tube and re-mill the head tube to the proper dimension. I have added shims cut from beer cans to tighten up oblong head tubes - but I don't know if this poses a safety issue. Seemed to work for as long as I had the bike (a couple of years). If you don't snug up the race/cup somehow then it just continues to get more and more worn...
