with the stock heads i'd say between -8 and -12 cc is what you are looking for with a stock 66.xx cc head.as orangeapeel said,check with a few vendors but i'm sure that will be close unless you use a different cc heads.

If you want to run that much boost, you may need to drop the Static CR even more (maybe 8.5:1). Also, as important as the number of cc's of dish, you will want to have a forged piston with a thick top land (area between the crown and the first compression ring).
You need to slow down and do some research on component selection and setup. Research some of the related threads in the forced induction forum.
