Gibson headers and exhaust?

[JBGabriel 10+ year member]

how long have u had them? ive heard nothing but complaints about pacesetters warping at the flanges.

I put them on in august. The flanges are just as thick as any other header i have seen. So far so good, no leaks. If they do warp ill just put regular manifolds on again cuz they were a ***** to put on. Had to jack up the motor and take off the starter and all kinds of fun stuff. Took me prolly 10 hrs to put both on. Gotta love ford modular motors.
