1992 Chassis Year began the "new" rounded body style, replacing 1977-91 style that was more squared. I know for a fact that Flowmaster had different "cat-back" exhaust systems for the two generations. That tells me they had to work with different configurations, probably to avoid interferences. I'd sooner believe that headers for the early generation with carb would work on early generation EFI, Than.. that late generation MPI would work on early generation EFI. Look up Exhaust Manifold Gaskets for the two 460's. If they're the same, the headers should bolt up. I doubt very seriously Ford changed the Firing Order, which would impact header effectiveness. As I said earlier in this thread, I believe the Carb-vs-EFI header issue has to do with connecting antipollution components.
