I just received my JBA headers and the flange is not flat. The welds are grinded but still sticking out. Is that normal, why is it not flat as magnaglows or factory? Also what’s the best gaskets for these headers. I’m replacing it 3th time now, I purchased magnaflows and they cracked after half year. Can someone recommend what to do?
I bought some cheap *** EBAY long pipes and they sucked like all hell to install and there is only 2 mm clearance from the left side to upper mount bracket but hey they work. got to say get remflex header gaskets no matter what your choice is. They are so thick but I will tell you what, after replaceing the ones that leaked 40k after headers, it quieted valvetrain noise by a million, it pads all resonance thru the headers from head and they are thick . what else can i say?
