I would hate to go through all that then having it all go to shit cuz the block is cracked.
You'll know if the block is cracked once you get it apart. Check the cylinder walls, if they filled with water before it was shut off then its broke more than likely. But, being as you said it won't crank over sounds like tthey're now full and not letting it turn over.

Pull the head and check it out. Sounds like you might get away with decking surfaces and putting it back together.

I didn't know about the thermostat shutting the car off if it sticks. Might as well put a new one in as well lol.
