Misfires Cylinder 1 - not head gasket?

Ok screenshots from my video. In order of cylinders 2, 1, 4, 1, 2, 3 Unfortunately cylinders 2 and 3 are up at the top so I can’t see the walls. I’m guessing the patchy crust is the result of fuel system cleaner? 4 looks smoothest but not shiny. The first picture of cylinder 1 shows the light reflecting off the liquid in the corners. I’m not sure why the board didn’t save them in the order I uploaded them, hence the random order here.
