I've got Headman long tube headers and have never had them drag. But I have very stiff front springs to account for lowering the front 2". I just went and looked, my header flange sits about 3/4" - 1" below the frame rail. Is that typical of what your guys' set up is?
I know that washing and waxing my car with the present condtion of my paint is like polishing a turd.....but it's my turd and I want it polished!
