Which long tube header that is not TTI suck the least?

I have fulllength Doug's headers on my daily driven '73 Dart.
They still hang lower than I hoped for.

Installing was a lot of work.
Engine position (up/down, left/right) is very important for the tubes to clear the torsion bars. I pulled the collectors together slightly when I welded up the X-pipe behind them.
Steering coupler can still contact the rear left tube.

I have a Borgeson power steering box which probably helped a, but I decided to use shims under the mounting to move the coupler away from the no.7 cylinder tube.

Also, their JetHot coating is GONE within one winter when roadsalt is used.
From the top, the headers still look new.
From the bottom, they look like they have been installed 6 years ago and totally rusted.
