I had a similar issue - the head tube on my Holdsworth Cyclone is quite short so a hanger would have obscured the badge.
Resorted to the old trick of drilling the stem:
View attachment 843268
NB. the stem is hollow so there's 2 holes that meet
1) Top surface perpendicular to be threaded and take the adjuster
2) Bottom surface parallel to the head tube
Using a Tange Levin CDS headset which is about 33.3mm stack and is visually a copy of an old Campy.
Also using the long verion of Mafac Racer (from Ebay France) so I can fit 700c Mavic Monthlery Pro tubulars.
