Ed,
That is, of course, something for every owner to decide or him/her-self.
It may be helpful to know that the bottom end actually has a more frequent
periodic maintenance than the top end...meaning that I think the factory
book calls for the rod journal bearings to be replaced every 25 k miles or
so, whereas the rings/liners are looked at when wear warrents, such as
blowby. At a minimum, you might do a plasti-gauge test of the bearings to
see that you're within acceptable tolerances. If you're not, maybe somebody
on the list can tell you how to check that your journals are not out of
round before simply replacing the bearings.
Any engine with blow-by as you describe inevitably has corresponding wear on
the other parts that will almost certainly require addressing before your
new liners give out.
Other factors include how long you intend to keep the car, how much...and
how far...you intend to drive it, and how closely you want to be monitoring
the condition of the bottom end to avoid catastrophic failure.
Your call, but either way, have fun!
