Early A V8 Headers/Exhaust

I don't believe a hydraulic clutch has a Z bar. I have an A 833 with Gear Vendors overdrive.

If I had realized how much of a PIA the Z bar and header clearance issues were going to be, I'd have gone with a hydraulic clutch also!
I have two 66 valiants. One with 833 and one with a tremec (obviously no zbar). The Doug’s I put in with an 833. The zbar setup I replaced with new stuff from Brewers.
