New Headers Installation

Couple of questions here. First question is will I have to remove the tie rods from my 72 Demon to install my new long tube Doug's headers? I am hoping that I can just lay them inside, tie them in place and lower the motor back in? The engine is currently out of the car, I have manual steering, and no power brakes. 2nd question, it is a 4-speed so will I need to modify my clutch linkage or purchase the Z-bar that TTI sells to clear the new headers?

Thanks for taking the time to help.
