I have never done an early motor, all my experience is with the late style. That being said, according to the early service manual, once the crank motor pulley is removed, the crankshaft will just slide out. This is the same as a late motor.
I have had some that are stuck pretty good. This is what I do in these cases. If it will not just slide out, I put the nut back on the end of the crank to protect the threads, then tap on the crank snout with a plastic dead blow hammer. If you do not have a dead blow hammer, I would put a block of wood on the crank and hit that with a ball-peen hammer.
