Headers for 440 /4-Speed combo

We're finally going hydraulic on my son's 440/4sp Dart this time around. We were given a pile of hydraulic clutch stuff including an 18-spline throwout bearing and the rest of the goodies. Just gotta get the engine finished and everything installed. We've fought Z-bar issues since I first built my old '67 hardtop with that drive train.
I’ve decided to go with a hydraulic clutch to cure the header / z-bar interference. But I’ll keep you in mind if that doesn’t work out and I end up going with different headers.
