Oh dear!!, headset/headtube problem

chris king make custom bevelled headsets to fit flared headtubes. worth the high price if its a rare/priccy/ emotional attachment, frame.
 
Just put a King in a 'new' frame and the bottom cup pushed in by hand and then moved the King to my Kahunna.Put a new Hope headset in the 'new' frame and had to use the press to get it in.

given the king tolerances I know what I'd be worried about. early rockshox king crown races could occasionally be loose fitting; again not a king problem ;)

I've used hope headsets, happy to get a year out of them & the bearings are toast.
 
Would it make you happier if I resprayed my Cannondale in coca cola livery pete hmmm? lol, thanks for all the help chaps at least I know I can get it sorted now thought I might have had to start looking for another frame I like. It is a strange headtube to be honest though its recessed slightly more around where the cups go in the original headset was a nice snug fit but has never been changed so made me wonder if headset and headtube were a funny size. Can't wait to get riding it again with all its new old bits lol will be like its been reborn.
 
is that a 1" head set?

there are 2 1" standards, the JIS and the more common European standard

The JIS head sets have a 27.0mm crown race and 30.0mm cups. The European standard 26.4mm crown race and 30.2mm cups. So a JIS cup would fit too loose in a standard head tube.
