fork selection help (for a 1 3/8", 25cm head tube)

I have to buy a fork to complete (or rather as the first building block for) a very nice Serotta steel and carbon frame.
But I am confounded by how long (and even how big a diameter)I need.
The head tube is 25cm long, 1 3/8" diameter. Period.
The seller says he was using a fork with a 30cm steering tube but that he found it a bit short and so used an adapter. I would like to avoid adapters.

But still, 5cm (2")
clearance seems sufficient ... (hmm, maybe not, standard stem seems to be 4cm tall. )
so, how much clearance should I be looking for once the races are installed?
the longest I am seeing on a carbon fork is 30mm.

and what's the steering tube diameter required for a 1 3/8" headtube? I have to imagine it's 1 1/8" no?
