You now have water and grit in the pan and along the pushrods and oil drain holes that go through the head. I would drop the pan and clean it. While the pan is off I would flush the rocker arms with diesel oil or other non-water solvent and catch the drippings in a pan below.
I am hoping someone has a better idea to get you out of this fix. You don't want to circulate that gunk through your oil system and bearings.

I'm most likely just gonna yank the engine out. Its one of the reasons I bought the truck. Learning to do a rebuild is something I've always wanted to do. I'm thinking when I dig deeper, I'm gonna find that the cylinders are toast. :-)
