RE: Best Fitting Header
Get your hands on a JEGGS or SUMMIT catalog. They have a good choice on headers and lots of other goodies. I would suggest ceramic or jet hot coating on the headers. That way they will last for a long long time and lower temps underhood. Good luck and take it easy. They also have the X-pipe and mandrel bent 2 1/2 to 3 " exhaust system that would be a great plus.
