Best suspension options???

Maybe so but that IS NOT the question! I want a suspension that will handle a Gen II Hemi with the
room they require. Those mods you are talking have nothing to do with fitting the engine in the chassis. We already know you can make the torsion bar setup handle well but that is NOT our concern! Now tell
me exactly how to easily accommodate the Hemi with the stock torsion bar setup.

Uh, actually, it IS the question that was asked in this thread. The OP isn't installing a hemi. So, yeah, none of the questions you have about your engine fitting the chassis are covered here. There are tons of threads on fitting hemi's in A-bodies. This isn't one of them.

Maybe you would be better served by starting your own thread and asking how to go about fitting the hemi you've got into the car you have. When you do that, it would also be helpful to say which car you have, what hemi you're installing, and what your goals for the car are. Just a thought.
