What are the symptoms if a set of heads don't match on a 400 small block?

You could find yourself with the same symtoms of bad head gaskets. You may find coolant in the oil as well as smoking from the exhaust.

400's have a nasty habit of cracking between the intake and exhaust valves on the middle 2 cylinders on the left head

That would be #3 and #5 cylinders. What is yours doing that is "crazy"?
