Okay, opened up the starboard side heads today. To me, they look really bad but I don't anything about engines. There is a grit in there, as well as some rust colored oil?

I think I know where the grit is from... when I was originally installing the engine after purchase, I tried to start it with the cowling on and the plugs out.... BOOM! Then I used the fire extinguisher and some overspray definitely entered the cylinders. I tried to clean it up best I could with seafoam, but never considered opening up the heads. I was a bit too timid to pull the heads and didn't know it was this easy or I would've cleaned it up a little better.

Anyway, I'm gonna wait to hear back from someone on what I should do next. It's not very easy to get to the flywheel through this optical ignition system, so I'll see if I can turn the prop and report back.
