I would say there is almost a millimetre or more if I can remember correctly.
I replaced mine with a standard 1" headset and carbon fork.
I had to use tinplate and wrap it around the headset then hammer it into headtube. It was tricky, its a dirty hack but it fits tight.
I have used it all winter for commuting, Rode it into a side of a car at reasonably fast speed which resulted in a buckled front wheel and bent handlebars. Fork and frame were fine.
However I am now thinking of taking it down to the track and a bit worried as there will be more force applied to the bars constantly which could pull the cups out.
What do you think the worst outcome could be? The cups come out and your fork is loose inside the headtube, the bike jerks and you lose control flying over the bars? :)

There is a mention of oversized Chris King cups. Did not think it was worth it for its purpose.
