Yes I think they are all interchangable, as long as its a 'big six'. I believe its the pre 80 heads that are prone to cracking. they have thinner metal above the exaust manifolds. the heat from the thermal reactors sometimes caused them to crack. Look on the head above the #2 intake port. there will be a round symbol with a two digit # inside the circle. the number is the date of man.
