For info on the A4-> M6 conversion, do a "search" on the "Drivetrain" forum.

The rest of your question isn't very clear. Appears you already have:
-slp shortie headers
-cut out
-lt4 conversion kit
-30 lbs injectors

Is this correct?

Then you appear to be considering the addition of either an ATI ProCharger or a Vortech, and running 8-12# of boost. Hopefully, not on a stock block.

Is this correct?

Then you want to select a good set of heads for the above combination? If you have the LT4 Conversion Kit, you alread have heads that would work with the rest of your parts and the blower. And you are looking at a torque converter, shifter, and new gears?

Not sure I understand the question.
