(a thousand dollar car I couldn't go wrong. The rest of the car is in great shape).
Here is my two cents:
The engine was definitely damaged, started with headgasket, blown
intake. Major one water disturbed the lubrication system. Consider a good investment when you finish putting it back together (no short cuts).
Find friends that can help: Tear the engine apart, cylinder heads, block to machine shop for cracks. It will be a slow process unless you have $$$ to get it done. Doing it with friends, accomplishment
you can look back (as Mustang expert). Forum friends will be glad to help, we are here for aggressive people like you. (goodluck)
