I'm thinking I may have the bearing cages in wrong. The instructional diagrams/explanations are unclear to me. I'll check them now.
Looks like balls down for the lower and balls up for the upper. Also there are some seals HS-RE006 you might be able to trap. The other thing to check is the clearance between the upper cover HS-HD003 and the upper cone HS-HD006. This varies depending on how much the collet on the upper cone has to compress to grip the steerer, and sometimes closes up completely when you tension the headset.
If the cover hits the upper cup, you can put a shim between the cover and the collet on most headsets, although I'm not sure from the diagram that this would work with Campag.
