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 in. higher and 3/8 in. 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 the angled spark plug location. What modifications will I need to make to the headers?

Hi:
Sorry but I don't have that info available to me. Try contacting the manufacturer of the headers. They should know what is needed.
