i use hooker 6113 fairlane headers on my 57 fairlane, they fit good EXCEPT i had to do a little clearance work on the lower driver side control arm. the pass side fit with minor grinding on the motor mount, i feel they fit better on my 57 than the fairlane they were made for. on my 58 i run an old set of hedman headers that were for a 69 mustang but are no longer available.
