Very Nice bike by the way.
Cinelli it seems somewhere between 1968 and 1971 updated the basic geometry of the Supercorsa.
This one looks like it will be a great all day bike.

Regarding the head badge, my take would be to leave it alone, IF the paint was better, It is not. The future for this bike will be a rechrome and repaint I think, the lugs are just too pretty in chrome.
Only way I would not rechrome would be if you went with yellow and red scheme, which while not correct for the bike is Cinelli and avoids the cost and risk of chrome.
