The blocks haven't warped. The reason for align boring is to correct main
bearing alignment from the factory. The Factory machined these in the only way
they could afford with their budget: the most cost effective way. The result
is the main bearings don't all line up and the crank will flex (or at least
until the bearings wear in). Align boring will set all the main bearings on
the
same axis allowing the crank to turn more freely and fles less resulting in a
more durable power plant.
If you're going to dump a couple grand into an engine rebuild it just makes
sense to do this as well as a balance. If nothing else it gives you bragging
rights! ;-)
