Service Engine Soon light flashing

Cel flashing
Ok I just pulled out the new plug it looked to be fouled out it has a little carbon build and looks to be a little wet. Can’t really tell what it is I was thinking gas due to a faint smell. But could it be water. I just replaced the head gaskets in April of last year. Not getting any other code besides the misfire on cylinder 6

Coolant doesn't have to be coming from a failed head gasket, it could be a cracked block behind the liner in 6. The next test is to get the engine up to operating temps, then pull plug 6 and inspect the combustion chamber with a cheap USB boroscope camera. You will then see where the likely coolant is entering from.
