Steel shim OE gasket. Just me I'd either clean the surfaces up & use the thin composition gaskets that are available & button it all up or clean it up & have the surfaces checked for flatness & use steel shim gaskets with alum spray paint which steel shim ones require flatness. Probably be better to check for flatness since you're already apart & you dont want to have to go in there again & I think I would go with the thin composition ones. Holler how it turns out

Oil looked a little dirty, and smelled a little gassy.
Here's the cylinder with the gasket still sitting on it.
Take a close look at the head surface and the block surface , hard to tell but it could have been leaking under the gasket , was the head surfaced during the rebuild ? How about the block ?

Like John said. Inspect that, and everything else closely.
Keep your antenna up. You need to find the problem before you start making assumptions or fixes. Even if you get new cylinder heads, and use a better gasket, you still need to find out exactly what is/was going on, IMO
The evidence is pretty convincing that water/coolant was getting into the combustion chamber, but if the source/cause is not obvious, I'm kinda wondering where all the cylinder pressure went. My very limited experience with small crack/water in the combustion chamber did not present the kind of cylinder pressure drop that you experianced.
Keep looking. Be sure to pull that piston as well.
