I am in agreement with your comments. However, the ones that receive more frequent oil changes will only have the thick varnish in the front head....not the sludge that you see here.The information is the reason people are doubting that is the primary issue. One side of the engine shows no sign of the oil change being overextended and the other appears to have suffered partial oil starvation. It looks a lot like an engine that had inadequate venting and suffered from moisture induced sludge but on one head only (That's an observation on appearance not an opinion on cause).
