If were me I'd check with Red's Headers. An independent dealer and he won't try to sell you something you don't want, need, or won't work in your application. I bought almost everything for my 8ba rebuild from Red's. High quality mostly USA made parts (the bearings were from Israel IIRC) and fair pricing IMO.
