You gave a good rundown, but you failed to talk about your transmission and your driving style.

First off, do you have a REAL transmission for this job, or just an automatic?

Secondly, are you one to spin it up to mid range RPM when pulling, or are you one that feels more comfortable keeping the RPM's down?

With an automatic I would keep the compression a LITTLE lower and use something like a COMP 252H. If it's a manual and you don't mind spinning it up some, I would stay with the same family, but move up to the 262H.

The KEY component that I looked for in your list of items was headers and I am assuming that you are running full length headers and not shorties. With full length headers, and low enough CR to run the Comp 252H, you might find a few of your friends that run 385's being envious of your low end torque.
