If you really want to know how to wake up your GM heads, go to www.motorbooks.com and look for David Vizard's book "How to Build and Modify Small Block Chevy Cylinder Heads" it is very well done and will allow you to mod your own heads for flow in the 240 cfm range, 260 if you are good. (As comparison, my CNC Heads ported LT1 flow 267 cfm , all flow figures referenced at .500 lift) Cylinder head porting is a little more involved than just getting advice on a message board, but it is a good place to start.
