Just recieved my dougs d450 headers Wowwww

Building a 408 for my 66 dart and need headers but dont want fenderwell headers. Not many options out there. Are these my best bet to try?? Any advantages over the tti beaders??
Yes, theses are nice but tti has a larger collector size. hooker has semi fenderwells also. I have them on my 65 cuda . very nice . have to cut small holes in fender wells those.
