Dougs Headers
I ran Dougs on a 65 Valiant I had years ago with a hot 360. They were hands down the easiest to install and best fitting headers I've ever owned. Follow the instructions, as a lot of things have to be removed to facilitate installation, but the fit and function is great. In fact, I didn't even have to have a V8 center link. My engine fit fine with the slant 6 center link. It was close, but it fit. I also used the Schumacher conversion mount kit as well.
