Rather than buy the full-on tuning kit which has a lot of parts you won't use, I suggest getting the metering rod spring kit and match rod actuation with your camshafts vacuum levels.

Then, if you think you need different rods and jets, consult the Edelbrock tuning manual.

Go here and scroll down: http://www.edelbrock.com/automotive_...ess_main.shtml

The information Edelbrock supplies will be pretty much right on the money.

Heed Tech's words about fuel pressure as well.
