Dougs Headers

I'm going in the reverse direction ... I want to remove my Doug's Headers and go back to stock 340 exhausts.

Anybody know where I can get the original stock headers?

Anybody have issues installing Doug's Headers recently on their small block cars? I have seen a couple of complaints that are not favorable and then some that really like them? Looking to install them on a 72 Demon with a 340 and a 4 speed. Would I be better off going with TTI or some other brand?

Thanks
