the only reliable manual for this info is the honda manual - you don't
mention what you have so my guess is that you googled here, saw the
usual [but learned from experience] reactions to the haynes crap, then
decided not to fess up to owning one.

regarding heads, the usual reason for removing both is that you need to
do the same clean-up on both. to be sure the job's done right that is.
just like most people replace the water pump when doing a timing belt.
however, unless there is some mechanical gotcha like connected
hardware, and provided there aren't any problems with your diagnosis as
to why you only want to change one, you can remove just one head and
you'll not notice any ill effects. but if your diagnosis is not
correct, you've just done a bunch of work that you'll have to do all
over again. why are you removing it? what is the problem?
