OK, so while I'm waiting for parts to come in, (rings and gaskets are here, still waiting for ball hone). Now, I've honed car engines before, but never tried porting and polishing. I thought since I have two identical heads from the clones, why not try porting and polishing one of them?

I started with 80 grit and was using 120 grit lapping compound for the second stage when I noticed what I thought was a deep gouge inside the exhaust port:

I was thinking how in the Hades did I do that? However, after taking a closer look, it appears that it's actually a crack in the exhaust port that extends to the outer edge:

I'm going over the rest of the head very carefully right now, but is this head toast?
