I wasn't aware there was such a thing as a Pamco rotor, lol. The Pamco is an ignition system that mounts up on the end of the cam, not down on the crank. I suppose you could call part that mounts on the end of the advance rod and spins above the Pamco plate a "rotor", but it just pushes on the end of the advance rod. It's not that tight a fit where a puller would be needed to remove it.
