Doug's and TTI both call for a modified Z-bar, it's right in the installation instructions on both. The Doug's headers can use the TTI modified Z-bar, so you can either modify your stock Z-bar to TTI specs or just buy one from TTI. I modified mine, it fits fine with my 340 and Doug's 453's.

And yes, you can remove the Z-bar with the engine and headers installed. I think you'll have to drop the starter to do it though, I can't remember. I know I've had my Z-bar off the car with the engine and headers installed though.

Here's what the modified z-bar looks like. Basically you take the arm for the clutch adjuster, cut it off the Z-bar, slide it down to the very end of the z bar and reverse it so that the clutch adjuster stud faces inside instead of out and weld the arm back on. It's a pretty simple operation if you have a welder.



Here's the specs on the stock and modified Z-bars. I labeled it Doug's because that's what I have, but it's from the TTI website. The full sized PDF file is below, but here's a screenshot of it so you can see the picture without a download if you're worried about that sort of thing.
