miling the heads?

Im working on my chevelle and am not pleased with the performance level. Its got 350 stock bottom end, Comp Cams 268(268/280, Lift .477/.480) Dart Iron Eagle heads 72cc, 165cc intake runners, 2.02x1.60 SS valves. edelbrock performer intake, Holley 650 DP, and hedman headers. The transmission is a turbo 350 with TCI shift kit and TCI breakaway 2200 torque converter. 3.55 gears out back. My concerns are the compression is way too low. It just seems like it doesnt set me back in my seat. It will break the tires loose but it dont pull very hard.My old weazy set up had 64cc heads and the smaller 1.94 valves. Would it be wise to mill the heads to get back down around 64cc again? Or is it cheaper to pawn the heads off and find some that are more fitting? Any input id appreciate guys. Thanks
