Seeing as you have the engine stripped that far down, you may as well take the barrel off & check the bottom end bearing, you would still have compression anyway. Cant see how you have no compression looking at the valves, seems very strange. I had a bike once that the front cylinder was about 15 - 20 psi less than the rear, but still ran fine.
As I said before, it's always worth determining where the noise is coming from. I have always used a screwdriver as a "stethoscope" & have been quite surprised where some rattles & bangs come from, but get exaggerated by the engine itself.
As Glang said, replace the plug, put the head with the valves facing upwards & pour some petrol into the head & see if it leaks
