well, what works with old soviet frames is to replace both the headset and fork with any modern one (JIS or ISO cups diameter - doesn't matter). what you have to prepared for is the fact the modern headset cups are loose in the headtube. this is easily addressed via shimming, and i have seen it work ;) many times. hope this helps.
