FWIW, just because the engine ingested water doesn't mean the whole thing needs to come apart. First thing I would do is pull the plugs, air filter, etc and crank it over by hand and make sure there is no water in the cylinders. The change the oil to make sure there is no water in it. Then try and crank it and see how it sounds. If all is good, fire it up. I have done this on a couple cars that ingested water and stalled. And with a little careful work, they started up and are still running fine.
