That's wrong, senior moment! I got to thinking about what I said and '59 and '60 heads CAN be interchanged -- if you use the distribution tubes in heads on 59 block and don't use them in heads on 60 block. The difference in reverse flow and conventional flow is in the block, that's where water passages are different.
