I did quite a bit of research before I chose these JBA headers. I have heard nothing but good things about JBA quality etc. I am disappointed with them, although it does look like they are well made. I am going to look at some of the Patriot headers again.I agree that it shouldn't be that hard for these companies to make headers that fit. It seems to be a fairly common occurrence on these forums that people have headers of different brands that don't fit.
