I just bought and installed BBK long tube headers on my 2 vavle. They seemed pretty good. But I just looked on some of the forums and everyone's saying they are garbage. But those posts where 4 years ago. A lot changes in 4 years, sometimes. A lot of things don't...I'm wondering if anyone has had a good experience with BBK long tube headers in the past year. Have they cleaned up their act? Or is it the same cheap parts that American Muscle has been pushing for years
