    the 74 probably wouldn't have them as they came about as an issue with UNLEADED gasoline---which wasn't an issue until starting about that time with cat converters--altho leaded gas was around for many more years and the trucks didn't have cats if they were above a certain gross wt rating

    If you have the D2TE-AA or D4TE heads on your 390, they came from the factory with induction hardened valve seats.
