340 in a 65 Dart, TTI HEADERS, H exhaust

Yep, I thank you for that info. Using a template from one side to the other on the crossmember. I was thinking about using a piece of steel pipe, cut to length, sawed in half, and welding it in place to accomodate the dual exhaust. Will that be all I need for adjustments for the dual exhaust in the 65? Thanks for the input. A small bit of my time, and with help from many, the car will get done. Old Dart 66
