oh god i want to try something like pic related for the upper headset bearing to try to tighten up the gap on top as well. the gap isn't absurdly big but needs some kind of rubber seal or o-ring to look the best it can. my frameset came with a normal 7mm thick bearing which seems to have the same stack height as the 6.5mm cheap chinese bearing. a ("campy style"?) angular contact bearing with the big ass chamfer might reduce the gap in the same way as for the lower bearing.
