    I'm not sure I have seen any logical reason to swap older 400-430 heads on (as long as they are stock vs stock). 430 heads would have additional oiling for solid rockers that isn't needed on a 455 with hollow pushrods.

    If you purchased the engine like this, it may be a few things.
    1. Previous owner had these heads worked on and they are not stock.
    2. Previous owner trashed the stock heads and needed replacements.
    3. Previous owner lost a race to a guy who had a 430
