452 Head question

By existing hardware I mean could I take my springs and valves out of my cracked head and use them on another head.(stock size valves) I'm still learning on these bb heads so I wasn't sure if all the 452 castings were the same with single springs and dampers, (have a set of junked 906's that don't have dampers) The 452's seem to have a different spring retainer also.

Not sure on dates I know my block is a 77, 40 over, so I know its been broke in to just wasn't sure about these heads and didn't want to buy another one and have to machine it.
