Wrapping my head around balancing

Sorry for another post about balance but i have to get it right in my head... my build will be an 01 magnum 5.9. Stock cast crank, either stock rods or Scat's probably bushed for floating pins, Wiseco or JE forged pistons 30 over and whatever bearings the crank needs. As I am changing the weight of the internals and therefore require an internal balance, am I correct in thinking that I can use the dampener and serp pulley off of a 5.2 magnum as well as that engine's flex plate because that motor is internally balanced? Also use a neutral balance converter? I know all the pieces will have to go to machine shop for balance. Thanx
