I would be concerned with the 1/2 mm gap on one side. I think you will have trouble in the future keeping the headset adjusted properly. I think you need to recut the race seat. I've been borrowing crown race cutters up till now but ordered one just yesterday on E-bay. If you want your nice bikes to be nice, you need nice tools. I ordered the Ice Toolz cutter for $262. I've not heard any bad reports about it and it's a LOT less than the Park tool.
