Yeah, 200k so might as well replace them. Christian said a few of his spark plug tubes were full of oil... eewww. Ben's were dry
Locktite??

...you used the soft stuff right?
Use a round punch with a good edge on it. Poke it through the top side of the cover. The seal has a steel outter ring so when your driving it out your not actually hitting the alloy cover. Hold the punch waaay over, almost touching the opposite side of the hole your accessing through. I had to hit it pretty hard too, all in one spot, didn't bother rotating around.
If you do nick the alloy just sand it out and put a dab of sealant on the outside of the seal. Oh, and don't forget the little half moons in the head that should be pulled, cleaned and re-silicone... two per side (if/when you do the gaskets)
I told Ben had we known the screws get loose like they do we'd started checking them at 50k cycles 150k ago!! lol ..
