Wow you have some big heads on that thing are you sure you numbers are right. chamber size are very big.

Call Bob Marada of Marine Kinetics he can help you. 585-654-8583

chambers are closer to 118 on standard bbc head.i like crane cams,hyd roller,or call bob [rmbuilder]and get a cam from him.as far as boost 8lbs is safe with your setup.
