Water in cylinder 4

[DSM315]

So here is my problem. Im having a misfire on cylinder 4. I parked it then went to start it and it wouldnt start. Pulled the plugs and water shot out then i put them back in and it started. I dont know where the water is coming from. It didnt feel like coolant at all just water.
(Cylinder 4. closest to transmission) just so were clear which cylinder if im wrong on the number

Tests i have done :
leak down . with radiator cap off and had no leaks in the cylinder and no bubbles from the coolant.

Coolant pressure test. coolant system tested fine. no leaks and the cylinder didnt get coolant or water in it.

History on the car.
been sitting since last year. got it running had a misfire. headgasket was just done last year with a fresh head from the machine shop. has cometic HG and arps. no coolant is running to the throttle body currently and when it runs with the misfire the plug in clyinder 4 gets wet and doesnt fire. car has been sitting a long time. maybe has 1 mile in 2 years and maybe 1 hour of run time.

Please let me know what you think.

How much water came out when you pulled #4 plug?

since it was parked for a year... could rain water some how got in there? Spark plug out? intake open? Hood left up?

it was filled right up. i was running the car last month. after i parked it it filled up. plugs were tight. hood was down. no rain water could have gotten in there. seems to only when it runs. or its gets warm.
