Sounds like you've done a lot of work chasing something that may not be a problem.
It is normal for a little bit of water to 'spit' at the joint to the turbo with a cold engine. Combustion produces water vapor - that's the white plume from the exhaust when you start the car on a cold day. With a cold engine, the moist exhaust condenses on the first bit of cold metal it sees - the turbo on a cold engine. That joint isn't perfect, but it tightens up as the parts warm up. And as the parts warm up, the moisture has to travel farther down the exhaust system until it finds some place to condense. Again, that's why you may even see water dripping from the cold muffler of a car.
So if you're getting a few drops of water at joints on a cold car, it's just the normal water by-product of gasoline combustion.
As to the mis-fire, I think you're looking in the wrong place. What do the spark plugs look like? If you had coolant in the cylinders, you'd see the plugs gummed up.
As a '92 9000, I'm guessing you've got Direct Ignition (DI). Misfire is a sign of a DI on the way out. See if you can get a known good one to drop in. Of course, you MUST be using the exact right NGK's as specified in the manual, gapped per the manual. There is a slight chance of the timing chain being set up wrong, but if you've swapped heads, I'd suspect that you've gotten that right on installation.
If you aren't losing coolant, then I'd say the water is normal, and your misfire is probably ignition problems.
