Revved hard and high and went out to take a whiff and it smelt dare i say like a sweet spice? Cinnamon...ish?
I know doing my valve covers are no where near the heads, but I was going to do water pump and timing belt. And at that point I am close to my heads, and would need to redo all those upper gaskets anyways.
It's one of those do I spend 500 to do VC and timing vs 1200 to do VC, timing, and heads. Or worse do first option only to do second option a few months down the road...

Here's my take on it. I'm at 385k and thinking the same as you. But in the end, if you are not actually using coolant, then you don't have a gasket problem. I have the same random puff of white smoke in the morning sometimes, but my truck does not use noticeable amount of coolant in the past 5 years since I replaced the water pump/tb. I have added about a quart of coolant in that time. I say just fix what you know is broken.
Save money for down the line, or do a block test if you are really worried about it. These engines run forever if you take care of them. I think most HG's go as a result of the radiator or WP leaking and running low on coolant and overheating. I was super worried about mine as I overheated it 1 time at about 355k, but the past 30k has been flawless.
