I read in the Muir book (Bentley doesn't speak to this issue) that if one
were just servicing the heads then you should be very careful to make sure
the cylinders do not pull away from the case when removing the cylinder
head.  What is the basis for this statement?  Is it just that it is more a
PITA if it slips off?

So here is my naive question: If I pull the #2 P/C to check the bore, aside
from keeping the internals clean, is there anything else I need to be
concerned about when I reinstall the P/C again (whether I reuse or get a
new one)?

Yes, they are 85.5.  My engine builder sourced new ones from someplace.

Part of me is of the mindset that if I already have the engine out and it
will take minimal effort at this point to replace the P/Cs that perhaps
that is wise.  It is not like I am using OG P/Cs and I think my builder
only charged me ~ $165 for the current set--so they are likely a budget set
as-is.

I will likely do what you suggest, Jim, and start with the #2 P/C and check
its bore.  If it shows too much wear, I am inclined to replace all 4.  If I
go that route, what kind should I buy for a stock application (forged vs.
cast) and new chinese-made vs. old (and probably expensive) german (or
maybe brazilian)?
