Tubular Automotive are a very nice header. Well made and easy to install.
Easiest headers I have ever installed. I did not have to lift the engine or remove torsion bars or steering linkage. Just need to know the right order and angle to put them on each side. I ran the 1 7/8' version with adapters for my W2 setup in a 70 Dart which was strictly a bracket racing car. Page 11 of their catalog. TDR 8 is their part number. The head mating flange can be made for standard head or W2.
This model is designed for the strip and do not have a collector flange and are a multi-piece design on each side. A collector flange can be welded on for exhaust hookup. They do sit a bit low in the back. TTI or other brands with collector flanges may be a more street friendly header for ground clearance and the rest of the exhaust setup.
