What's the solution in this case? A different lower bearing with a different angle?
If that's where the error lies, then yes. It needs checking with a goniometer. That might not be the issue, it could be that the fork crown is way out of tolerance. Having once been viciously attacked by whichever monkey tried to make it fit, it certainly needs close inspection for any damage.
The only things which should move perceptibly when you preload the headset are the compression ring, upper bearing cover, stem, spacer stack and top cap. Everything below that should already be fully seated and the only movement will be imperceptible elastic compression of the balls and races.
