Haven't done it on a Honda engine, but the general rule is that the
crankshaft has to come out to get the pistons out the bottom.
If you don't have something known to be seriously wrong with the pistons,
for the love of your sanity leave them be. They are fine if you aren't
burning a lot of oil, and disturbing them will only make things worse. Honda
rings typically last the life of the car if you change the oil regularly and
don't make the engine "ping." If they need work it has to be done properly,
and that means big bucks.
Since the head is off, take it to a machine shop - preferably one that
specializes in cylinder heads - to have it checked for flatness and to have
the valve seals replaced. When you put the head on, be sure to follow the
instructions regarding cleanliness of the mating surfaces, tightening
sequence and torque. The head gasket and manifold gaskets must be replaced
any time the head is removed.
