They did mill the head but I do not know how much was necessary
Just did HG with all the goodies and still loosing coolant : (

Ok, that's a little more! Something more than trapped air bubbles.

Yeah unfortunately that's what I'm thinking too
Heater core is the only thing not visable at this point.
Does your local part store rent out a radiator pressure tester?

Have you tried burning off the condensate in the oil, dump it & swap fresh oil - just to prove out it's going there?
Or have you had ~2 oil changes since the refresh gasket & this keeps eating coolant?
Did it run proper at all, or is this straight up how it has been since the HG work?

I though about the heater core but I don't smell anything in the cab and I did shine the UV light under the dash and in the passenger side foot well looking for dye and didn't notice anything.

Only one oil change since the hg. I noticed a small amount of goop under the oil cap 3 days after the work was finished and thought it might be a small amount of residual coolant burning off but a week after the work the goop was much worse. The goop wouldn't worry me at all especially this time of year if not for the coolant loss.
Is it common for the head gasket to be this mis-shaped around the cylinder? Looking @ the 3rd pic in the post, that gasket is all kinds of not round!

I don't think so, I don't see how it could be. It was obvious that someone had been in there before.
Running super/92 & Techron treatmemt can lift the carbon if that's what you see (I'm on a phone, riding highway)
Just saying as I borescoped mine yrs ago (new tool in refinery, I wanted to play with)- to see if Techron did as claimed (it does, but you gotta run a bottle every 1000-1500mi to keep spotless). But it does do the piston tops, I expect the valve bells cleanup too. Just my experience.
And blowing a HG (guessing #6 blew) - fogs you a good 'steam-clean' on that one. IDK.
I do recall a couple days in atmosphere with the head off mine & carbon on the pistons (pre HG, regular 87 & no Techron, ~2002/03) peeled up like latex paint & lifted spotless with a rag & WD.
Maybe I missed it, but is it running hot and/or overheating?
Firm believer in techron as well, great stuff! Neighbor owned a Chevron forever and brought us a bottle here and there. Helps ever so slightly for smog as well. I always try to run some after a trip with a random gas station stop, keep the path clean on the top end.
Just a thought, but are other cylinders overly large or out of round on the gasket? If so, I could be to take up some added cc space from a deck height job, if, that wasn't achieved by the hg thickness? .02¢
Hi, I'd try swapping in a good oil cooler and see what happens. Visual inspection might not be good enough. Mike

Mine did exactly that, peeled up and flaked right off. First pic is immediately after the head came off. Second pic is a couple days later.

Yes there were a couple more that did look very out of round, struck me as odd right off the bat.

That's what I have been hoping since I initially started loosing coolant. Just figured since I was going to have the manifold off might as well go ahead and do the hg as well. You bring up a good point about the visual inspection might not being enough, say it was cracked shouldn't I be getting some oil in the coolant as well?
If I recall, New head gaskets are out of round there too.

The truck has never ran hot or overheated since I've owned it
