I think post three kind of covered it? Putting small dents in these headers is a very commonplace in a body Mopars.
A few people get away with not denting them, but most don't.. Of course it always hurts worse when you paid more for the stuff...
A special message is there at 2 minutes and 10 seconds...
I have installed a good number of TTI headers on 67-76 A bodies and the only set l had to dent was on a car with home made motor mounts. This includes different power steering boxes and torsion bars as large as 1.14”.
I used to think TTI was over priced until my friend had a custom set of stainless built for his car ...cost was more than the last engine I built.
