my undersatanding that aircraft engines have a calendar TBO as well as a
tach TBO. however, prices for these aircraft do not seem to reflect
engines that are beyond TBO. Is calendar TBO something that is generally
ignored?

Yes, and certainly a seller in that position is going to do his best to ignore it.

Should a prospective buyer make a hard negotiating point about it?

As a buyer, I would certainly include it in my personal calculation of what I
would pay. You're missing out on 20 years of engineering changes, for one thing.
For another, it's probably had a lot of idle time for camshaft corrosion to
get a grip.

OTOH, assuming the price is adjusted appropriately, I'd prefer to buy a plane
with a runout engine and have it overhauled on my terms.
