I have a 78 F-250 with a 302 i bought headers and one is in the way of the front driveshaft can it be bent or will it have to be cut and pipe added any suggestions ?

If you can bend the header without kinking the tubes too bad, it should be O.K. If not, it may be best to cut and add lengths.

The more you kink/distort it, the more it restricts exhaust flow.
