Headset cup removal problem (self.bikewrench)

Hoping someone can offer some advice. I'm working on a late 80s Raleigh Montage, 88 I think. It has a u-brake on the rear which dates it.

Anyway I have it all stripped down, including the cup and cone bb.

The only thing I can't seem to remove are the headset cups, as the headtube is slightly flared on the inside top and bottom, so I can't get the tool to make contact with the edge of the cup.

What am I missing here? How do I get these out?

Hmm. I see what you mean, the cup edge is partially recessed. Something like this may work, but a solid bit of rod will do the trick: https://www.instructables.com/Bicycle-Headset-Cup-Removal-Tool-1/

Try to grip the frame as close to the headset as possible, that way less of your upwards tapping force isn't getting lost to frame flex etc. Dry ice can also help, from local grocery store.
