Could be oil and/or overly rich mixture.
Did you do a compression test beforehand? That might give you a clue.
In the first picture, the lower coolant ports are completely blocked, compared to the upper ports. Did you clean/open the upper ports?

what are you wanting to do with this thing? are you looking to rebuild the bottom end? It definitely had something going into the combustion chambers. I agree with Gmag, it could be oil could be fuel.
