Look closely at the discolored areas on the head. Done of the areas look great, like they sealed up correctly. Other areas look like they were potentially leaking into two cylinders. Could be either around or through the head gasket.But from where?

Not going to run a thick composite head gasket at 20 psi.With that piston deck height, I would be sure to run a thick composite head gasket.
Cylinders I have seen that had a coolant leak were clean like the 3 in your pics. The one cyl with color was not getting coolant, my interpretation.
I would be OCD on tightening sequence and tq steps on heads after that episode.
Good luck on getting it right and enjoying.
