What headers for Big Block Scamp

There might be an issue with the stock z-bar using TTI's on a 440. The Shumachers will work with a stock z-bar as far as I know. When I installed 2" TTI's on my 440 I dropped the k-frame/front suspension, installed engine/headers/trans as a complete unit. To get a wrench on the passenger side looks nearly impossible. My car is a 68 Dart.
