OK, I have to put in my 2 cents worth. First off, Don, this is just a FYI. I talked to Clifford on the phone, yesterday, about a few things. They have header flanges available, for $40.00, their part number is 75-0016. Their phone number is 1-888-471-1161.
I am not going to knock the power pipes, because I don't have any idea if they work or not. I have been told, more then once, an idea of mine wouldn't work and it did. Even if they are not better then a stock manifold, they do have a use. What about someone builing a low dollar street rod? Dutra's are pricey, Off the shelf headers, most likley, will not fit, and a stock manifold looks yuckky. That said, unless I missed something, I would like to see a comparison of the power pipe to a stock manifold, with no other changes. Either track times, or engine/chassis dyno numbers.
