I would certainly change them and have done so when I've replaced head gaskets on my vehicles. They don't cost much.
If you are adept at 'reading' plugs, and they look ok, and you clean them, and you re-gap them to specs, MAYBE it would be fine to reuse your old ones. But to me it's cheaper just to replace these items which do wear out over time anyway.
Some spark plugs in some engines have an expected 100,000 miles' life to them. But I'd change them anyway while I was down and dirty doing the the head gasket work.

How do you change the spark plugs on a 2005 Nissan Murano?
The first three spark plugs (bank1) are simple, unplug then remove the ignition coils, and the spark plugs from there should be easily accessible. Now the harder part. The complete upper intake manifold (plenum) needs to be removed to access the rear (bank2) plugs (3 there). After removing, you should gain access to the other 3 coils. Unplug and remove the other 3 coils then remove the plugs. Any time the intake manifold is removed, you must replace the gasket, so make sure you replace the manifold gasket before putting it back together.
