Headers VS Manifolds

Dave....you are using the stainless header on a NEON?...all good but how does that relate to using them on a 66 with a v8? I missed something in your reply??? do you know someone that used them on a 66 barracuda, Valiant or Dart with a v8 340, 318, or 273 engine and a 727 trans that was never designed to be in this narrow wonder?
