- Will not fit motors equipped with air injection pump without modification.
- Hooker headers for MOPAR 383-440 engines will bolt on the popular aftermarket B-S heads. However, because the exhaust port centerline on these heads is 5/8' higher and 3/8' out from the engine centerline compared to stock heads, some header modifications will be required for installation. Custom header applications will be required to fit the B-1 heads because of angled spark plug location.
