Didnt know if anyone had used these headers with the JTR setup but.....I decided to chance it and bought a set of their cheap raw material block huggers and they fit perfect with the JTR setup, pretty thick flanges, 1 5/8 primaries, 2.5" collectors, a little 2k degree black header paint and they look excellent .....I think they were $85 dollars........sorry about the camera phone pics.....
