One last closing note ... I just took it out for a drive. I definetly feel a slight loss in low end torque, but it's WAY quieter and my once perceived lifter tick is GONE! The latter had to have been due to the missing bolt on the bottom / midde right side; the gasket had also showed sure signs of an exhaust manifold leak.
I suppose the Banks manifold MAY in favt provide a slight gain in toqrue, but now my Jeep purrs like a kitten and sound how a Jeep is suppose to sound. I did not think that I could get it to drive any smoother after I had foxed my pinion angle, but somehow I did.
I'll put it around town a bit more before I take her on a longer road trip, just to make sure everything is fine. Looking good like I said so far though, it's been a hell of a last few days quite literally, so I'm considering this as a tattoo for positive inspiration in the future:
