If needed, cut the pin ends off with a dremel.
I also had a brutal time getting this roll pin out.
As Tom K said, the nail head just expanded the roll pin. So I did as Matt said & used a dremel tool to very carefully cut off one mushroomed end. Then I got a nail long enough to reach past the well of the drum cavity (so I could hammer it without damaging the hull). I ground the nail down to the exact diameter of the roll pin (1/8 "). I ground the nail tip flat & perpendicular, lubed the pin up w/ WD-40 & gently hammered it through with the nail. Fortunately I had enough material on the other end to grab it with a vice grip & the push/pull worked.
I replaced with a SS cotter pin.
Good luck.
