New Pistons, is the motor still balanced?

I have a .060 over 496 that sounds like a diesel so I pulled it apart and found the piston to wall clearance to be between .005 and .006. The pistons are flat top KB hypercracktics. If I have the block bored to the right size for a new set of .070 identical KB pistons that I already own and If I weigh each rod and piston from my .060 assembly and match it to the .070 rod and piston weight, would it still be balanced?

Thanks for the good advice I'm sure I'll be getting.
