Extremely pleased with Dougs headers
Oh, and I'll add this to the conversation. The Dougs headers I used when I had my 65 Valiant were hands DOWN the easiest set I have ever installed on anything. BAR NONE. And I got one of the first 25 sets when they came back out with them. They actually made them differently than they do now and still called them the "D Dart" headers. The box even came stamped "D DART". This was probably about 1995. I talked to Doug Thorley (RIP) hisself many times on the phone before, during and after they got them from R&D to the finished product. MAN could that old dude ever talk. But he was the coolest old guy you'd ever wanna talk to.
