if you want to be serious about it and building race motor you would re balance whole motor again.it is correct way to do things.
in real world difference is not great enough to make it necessary ,you can get away without doing it.
you need to hone it out until you get proper clearance.clearance can be found in manual.there is range,pick number in there and go for it.engine builders pick number that they believe will give them best clearance for intended use.and you can't find 2 of them to agree
