    all long tube headers make about the same rear wheel horsepower.

    doesnt it matter on your engine?!?!?!/1 for example...if you have more than 380 cubes... 1 7/8 or 2 inch headers are better than the regular 1 3/8's

    That is correct, not all long tube headers are going to make the same power, maybe close, but if you are picking a few ponies here and there, you can find a few in different header designs.

    Tuned length primary pipes, primary pipe diameter, stepped primary pipe diameters, collector diameter, collector length, try-Y, etc etc....there are so many designs, and power will vary with each depending alot on the engine combination you are running as well.
