Worth the hassle? Probably, but maybe as a winter project rather than
something to get done before next weekend's event.
On rebalancing, my very much hearsay experience is probably yes -- and if
you have the engine out as a winter project, why not? Possibly, if you have
all pistons balanced to each other already, all you need to do is balance
the flywheel assembly itself. If pistons and flywheel were balanced as a
unit, then they all need to be rebalanced together. And if I am talking
through my hat there, someone more knowledgeable will surely jump in and
correct me.

I'm the latter.)
