Does your oil look ok on the dipstick? It will go milky if there's water. Check immediately after shutting down engine so it's well mixed.
The oil looks good. This is strange, exhaust looks and smells normal too.
I'm planning to do a cam swap next year, if I don't have it figured out by then, I'll probably just pull the heads and replace the gaskets at the same time.
