Oil on pistons?

I agree that plug looks extremely rich especially after only 1 hr of running. What I don't know is whether oil intrusion into the cylinder can cause a plug to look like that after only 1 hr of run time. What you think? I still think he has oil being sucked into the cylinder whether it be from bad intake manifold seal, blown head gasket, valve seals, rings or whatever else. I think that amount of oil after shutdown is unusual. I am curious whether all cylinders show that oil.

All cylinders each one has that in them exactly they are all exactly the same. So I don't think it's a bad seal from the manifold.. I think the previous posters and you are right I'm running extremely rich. I'm trying g to see how many jet sizes I need to drop, do that, change oil, and put more timing in it. Would it be smart to put new plugs in it as well?
