Don and all,
Thanks for posting the photo--its hard to argue with the facts. I'm not sure if yours is representative of all Tange headsets, however. The fit between crown race and cup on the Tange Levin headset that I have looks like the Campy headset you showed. Are you sure that the Tange parts were originally mated, or did they come from separate batches?
