If it were me, I would pull the head off, won't hurt to clean the carbon off the head, pistons & valves. You can spray penetrating oil into the stuck valves & try to tap them down. If you succeed then spray carb cleaner on the valve stem to get the gunk out and relubricate again. You can work all the valves by turning the engine over.Most of the time it's the dry gunk that freezes up the valves.
