BB motor mount/Zbar help diagnosing

Hey all.

72 Demon 440 A833
Trans Dapt slant 6 K to RB motor mount kit
Moroso solid biscuit mounts
TTI 1 3/4" headers


Now the story. I had ancient homemade solid engine mounts. One of them broke. That setup wasn't ideal and I wanted something "better". The setup worked well for 3 years of abuse. I decided to get the trans dapt slant 6 to RB engine mount kit and use Moroso solid biscuit mounts over the rubber biscuit mounts provided. I test fitted everything, so I thought, with eh new mounts. All looked great. so I pulled the works and did some cleanup on the engine. Now I have it all dropped back in place. Engine sits a little lower than before. Which I thought would be great, since the valve cover was hitting my bulkhead for the wiring harness. Now that the engine and trans a set down where they look comfortable. I am trying to hookup the headers and Zbar. The header fits but the Zbar does not function. It hits the header where the rod for the clutch fork goes. Also pulls the Zbar away from the frame rail mount and falls off the ball stud. So I reset and started over. I put the Zbar back in the correct spot and bolted it to the bell housing. That worked great. Now the header doesn't come up high enough, unless the Zbar gets moved out of position again.

Any of you BB four speed guys running the factory stuff have any tips? Once again, this setup worked before but the mount broke. So instead of making a new mount I decided to go with a kit that people say works. If I was capable I would post pics but not the case. LOL

Anyway hope someone can give me a tip.
