Thanks for the reply - was tracking these should be 915 heads as well. So this is the only numbers I could see with the rockers on - these would be incorrect heads then?
Heads won't give you the info your looking for. Need to get under the car and check the casting #'s and look for the shipping order number stamped on the side of the block just above the oil pan. 67 R/T 440's should have 915 heads...which are the last 3 numbers of the casting numbers.
Those heads are 1972 ish heads. You have to do as Nate S described above, to check the block for correctness.
