I think there's a good a good chance of a stuck intake valve. I only say this because that's probably how the water got into the cylinder in the first place. You might try adjusting it loose and try the Berryman's trick of pouring it into the intake while the motor runs.

But before you do that, if you have access to an air compressor try the trick of filling the cylinder with air when it's at TDC and listen for the leaks at intake, exhaust, and crankcase. This will point you in the right direction.

The rest of your numbers look pretty good.
