Flywheel balance?

Doin the a-4 to M6 swap.. heres a little back story..
got a new motor Lt1 383 stroker, can't put it in till christmas. (its in Mich.. im in Nc) but my tranny started throwing codes.. so i picked up a M6 swap.
it came out of a 94 camaro, and my cars a 96. the clutch still has some life in it, and i am going to use it till i put the motor in, when i can get a nice Spec, or centerforce.
With the Flywheel, clutch and pressure plate out of a Lt1 car before. going into a Lt1 car, would i need the flywheel rebalanced to the motor i have in the car now or would i just line the pins up and bolt her down?
when i do change the new motor, would i need to have the flywheel rebalanced for the 383 due to it being Centrally balanced, or will it not be a factor?
Thanks!
