If you are simply honing and reringing, no. If you are doing it the right way, yes.

Then yes. Boring the block means different weight pistons. Balance everything for long life.

I had mine balanced...I don't regret it.
With new 1st over pistons, re-ground crank, re-sized rods, ARP rod bolts, I thought it wise to be safe, not sorry...and now I am glad I had it all balanced.
It is a small price to pay for peace of mind and a smooth running engine..IMO

If your changing bearings and ring types manufacturer, all this is included in a GOOD balance - so YES you need to have it rebalanced.
Would I even if I wasn't changing the above....YES

If you are going to push it at all, balancing is a must for longivity
