TTI header woes

I know they have at least one or more front frames either with or without the inner fender wells attached, that they originally used to design the headers with their engine mounts. I kinda doubt they had the brake valve bolted in place when they did this. My valve was in the way but I would have had no problem moving it if that was the only problem. I would have had to severely smash a header tube to clear the driver side torsion bar. I had to do that on an old set of Hedman headers for an old 440 Plymouth I had when I was 19 years old. I wasn't about to do that 50 years later on my Cuda.
