'67 coupe 289 smoking issues

My 289 recently started smoking more and more. It's a white/bluefish smoke and I still have a ticking noise in there somewhere. I'm assuming they are related.
Here's what I have done... Checked and replaced worn lifters, lubed all lifters with moly grease, adjusted valves, removed cleaned and painted exhaust manifold, replaced donut gasket at rear of ex manifold, removed and checked plugs... Here's where im having issues. Plugs looked good except for a couple issues. A couple of them have oily deposits around the threads.

What should I check next? Valve guides, seals, rings??? I'm trying to be as thorough as possible before I have to take it to someone.
I don't mind tearing it all apart to find it, I look at it as a learning experience. I would really appreciate the help.
Thanks everyone

Sounds like a busted ring but the ticking makes me think bottom end... I'd get a compression or leak down tester and ho from there

Could the valve cover gaskets be leaking, getting oil on the exhaust? Plugs don't look that bad but the residue on the base looks like something external.

Sounds a lot like valve stem seals too. Could be guides They can only be checked with the head off and springs removed. Best done by a machine shop. Rings or valve seals/guides can give similar symptoms.

By the way, "ticking" is usually used to describe a lighter sound which is generally valve train related. "Knocking" is usually associated with bottom end noises like bearing or wrist pin. Worn rings don't usually make any noise on their own. If left unfixed, other things will get noisy. The oily plugs are that way because of too much oil in the combustion chamber. It sounds like you are ready for a rebuild.
