ignition will work. It'll run with the 440 pipe, it'll just burn down on your first high speed run. The outlet diameter is too small. Depends what year cases you're dealing with for how easy it is to make it 600. Search around, tons of info.

yes you can put 60 cylinders on a '02 bottom, however you will not have a true 600 when you are all done. heres why, the 440 stroke is shorter than a 600, the cranks are the same other than that little detail. if you were going to do it i think i would have the crank welded, its not made for the additional HP the 600 top end might throw at it, may or may not last long is all.
so you will need 600 cylinders, exhaust valves, carbs and cable, head, cover, 600 pro x y pipe, pipe, and a silence for any 600 edge sled(silencer bracket needs to moded for it to fit), a new grommet for the bellypan for a 600 exhaust pipe to fit thru it, a 600 style fuel pump or a T fitting to hook the 2 outlets on your 440 pump together.
and 600 clutch parts.
ya thats all i can think of.
good luck
