I found the engine location guide per TTi's website. I'd rather not pursue the dent the header route as it has more manual labor involved, but we'll see what happens.
Should take about an hour at most to drop a driver's side TTI header, at least it would in an ebody[?]. Drop it, press/bang it and go back together. The engine will move quite a bit on those mounts, you need sufficient clearance in a static and dynamic running state....FWIW i have a chromoly torque strap on my engine [which doesn't help NVH], the same transmission and zero drone. It's not much of a mystery, keep it from rubbing and put some decent mufflers on it.
IMO, if you aren't already, I suggest you take just a couple of trusted Moparts opinions and use them as your guidance. You can go round-and-round chasing rabbits within a large thread like this....
