This is one where it makes sense to use the right tool (either homemade or borrowed) because the fit and quality of the headset can significantly affect ride quality.
Just took care of this today! I took the advice of RJ and made a homemade tool out of a conduit pipe, it worked like a charm! Do you know if that was natural corrosion that caused those to stay in, or simply friction, or do I need to use some sort of adhesive when I reattach them? Thanks to you, my frame is now (actually) completely ready haha.
