Fender well headers

Like I said the holes they tell you to cut are only for installation. Once they are in there your going to want to cover the 6" gaps with a patch panel. Id recommend screwing the headers into the fenderwell holes before the motor because once you get them in place youll have <1/2 inches on the passenger side to move those headers around, and that is the easy side!

WHY! fenderwells?

because he bought them! C'mon.....Im sure he thought this through before dropping >$600 on a set of headers. He's asking for guidance, not grief counseling.
