your fork crown race and lower cup need replacing at the least. your headset has what's known as "brinnelling".
b4 there was rockwell hardness testing of metals. a Dr. Brinnel determined a way to test for hardness what he did was to fire
bullets at different speeds into a test piece and measure the deformations. when a bearing sueface is ruined by
gouging it is called "galling" when it is indented ball bearings it is called "brinneling" it often happens when the bearing adjustment
is too tight but a too loose adjustment will cause it also. adjust your bearings neither too tight or too loose
for longest lasting service.
