How bad?

Looks like I was right all along. The gasket looks fine to me. At least I get a peek in the cylinders. Now, I am curious about the buildup on the pistons in so few miles( maybe 400). Could it just be from the time it spent running high 10's to low 11's AFR? Or was it sucking oil? I didn't seem to be losing any.
What do you guys think?
I didn't read your whole post initially, but was thinking it might be rich. And now I see it was. I would not sweat it at this point.

As far as the head gasket(s), you are not going to reuse it (them), correct?
