I almost hate to say what I'm going to say, BUT, I have a 360 Magnum in my '72 Valiant and ordered if TTI headers for it, installed them with no problems, whatsoever; didn't even have to loosen the motor mount bolts.
I DID install a mini-starter at that time.
Everything fit "as advertised" with no interference. My car has power steering and no TTI motor mounts (stock rubber.)
