A couple years ago it woke up with a misfire. But that went away after an Italian tune-up. Keep in mind these are very robust engines, maybe if it was an S54 I would be more concerned.
My main concern was that if the cylinders were dry of oil there might be some scuffing. Much less load if the plugs were out for a few revs.

Thanks to all your responses. I most likely will follow your advice. Pulling plugs that have been seated for many years can cause MAJOR problems.
