I know this topic is a common one, and beat to death and I did look at past threads to see what I could learn and did get some good advice doing so. I would still like to ask however those with 70-72 years, SB engines and AFR heads, with SQUARE exhaust ports, what headers those of you had success with. I am in the market for new headers and don't want a repeat of the issue's I have currently with poorly matching headers that leak and that also work well in regards to clearances without modifications.
