Installed a set of 11150flt headers into my 1970 Cutlass Supreme 350 floorshift auto.....2nd cylinder of header pipe on passenger side hangs 1.5 or so inches lower than the old ones i have one there old headers are brand unknown and hit the top of the crossmember...this dont make sence as the list this in summit sit to fit....is this a manufacturing issure because now i cant return them and i would have to really flatten them out to fit....

Each header manufacturer does it different.

So i had to beat in 1st and 2nd cylinder tube half inch each or so to get it to work....as both were hitting the top crossmember.....Had to modify the motor mount on the corner cut a some off, its a old mount so not to worried about it......also had to pound that part of the pipe in too....my buddy was telling me get the ceramic coated ones hahha...man am i glad i didn't.....but they in now sitting flush......i gotta say your right all manufacturers are different but they all still need to fit and these are junk.....
