Re: installed steering head bearing backwards
"how the hell can i salvage this?"
I sense that the issue is not how to remove the race but rather how to remove it undamaged so that you can correctly install it - because otherwise you'll have to buy a whole new bearing. Unfortunately, you may be screwed.
If you have the old bearing, you might be able to cut the retainer/balls into sections that can be fitted into the new upside-down outer race; perhaps with a couple fewer balls. Then set the old inner race in place from the inside, i.e. through the other end of the steering head, and use it to drive the new race out. You'll be lucky if this works.
P.S. I couldn't tell at first but I now gather from the part number on the race that it's an All Balls roller bearing race instead of an original angular contact ball bearing. That complicates things. You might check if the old retainer/balls are wide enough to "catch" the race when inserted from the backside. If so, drive it out per above and hopefully the race won't be damaged. If not, use Dremel grinding stones and abrasive discs to cut two steps on opposite sides of the race and use a punch to drive the race out.
