If you are planning on making bigger power, I have Steve Coombes' old 2-piece flange Hedman Hussler headers. These were on his '70 Trans Am, back when he was still running D-ports. I believe 2" primaries and 3.5" collectors.
I had planned on going more radical with my car, at one time, but now don't think I'll ever have a need for these headers.
