Re: double hump heads on a 78 engine
that is a lot of unknowns , especially since with todays after market aluminum heads the Double humps are dinosaurs and obsolete to most guys.
but they should work fine on a 78 , do they have the accessory bracket bolt holes??
I think pre 69 or 67 or so had no holes for brackets
