They really don't require much to put them on a 408. The pistons already have reliefs so you should be good on PTV. However, it's always a good idea to check how much you actually have. Other than that, the heads will bolt right on. Remember that intake rockers, rocker pedestals, intake, fuel rails, etc. will all change from the factory LS1 style with these heads. Let me know if we can help with anything!
