Original Super Stock HEMI Barracuda BO29

Finally starting to work on my 69 440 +6 manual transmission faker. I have seen some photo's of the engine bay with the HEMI in it but for some reason i can not see very well what the headers look like. As best as i can tell they were not fender well types. How did they get them in with such a big motor. What modifications were done if any? Still learning about Plymouth's as most of my life was about the cheaper G.M.'s to acquire.
