There is definitely something going on in the third cylinder it was quite wet

Tom,
Other than the valves, valve guides and spark plugs there aren't too many
other sources of little balls of molten metal as seen in your pics. When
pistons fail from events like detonation or connecting rod failure, they
usually
deposit chunks of aluminum on the piston top. These little pieces look like
they came from valves or guides. Whether the cylinder is "wet" from unburned
fuel or coolant, I think you need to address the head and also check the
block deck for true flat across the deck....of course, check the cylinder
walls
for scoring, etc.
