Hydrolock damage
No way would a leaky runner gasket raise the level that high, w/out being forced in, under psi....
Furthermore, there is more than 1 valve open, at anytime in the cycle, so more than 1 cyl had to have water in it, IF the intake full scenario is accurate.
Sumting wong w/ this story.
On the v6 cars the cowling ruins the coils(water shorts the ignition in the rain) and of course can get into the engine just like the v8 cars. I know of one car v6 the engine failed because of water in the oil, they replaced the engine and THE NEW ENGINE FAILED same way. They finally figured out the windshield cowling was letting water sit on the top of the engine and it was getting into the PCV opening in the top of the intake. If can find the video I'll post a link, been a while since I came across the posting.
Open your hood in the rain and look at the water dripping down all over the engine. The newer cars have covers over the top of the engines to prevent this and cut down on noise complaints.
