Try heating up the headstock with a heat gun (paint stripper). Mine came out with little force.

Did the same when putting in new ones.

G'day Allen.
I use a side hammer with a hook, alternating from side to side. https://www.ebay.com.au/itm/362928937776

Unless you can rule out the use of loctite (or similar) having been used on the outer race (due to loose fit) I think you should try heat......from memory loctite 609 softens between 100 and 200 degC. The good news is that if the race is being held by loctite it will come out easily once the loctite is soft.
