    the title pretty much says it all. I know there were some differences in coolant passages or something? but I don't know what years were different.

    Yes. Should be no problem. There really isn’t any improvement in compression or hp to be gained though

    Thanks Andy, was not looking at them for improvement. I am in the middle of a engine build, haven't done my heads yet but I found a set rebuilt.

    If your putting in a performance cam make sure the new heads have better springs or replace them before you bolt heads on
