Here is the cfm data for a set of stock LS7 heads;
Lift --Intake --Exhaust
.300--246 cfm--174 cfm
.400--302 cfm
--200 cfm
.500--343 cfm--211 cfm
.550--358 cfm--216 cfm
.600--360 cfm--220 cfm
Flow is extremely good stock and the Ls7 heads have a 70cc combustion chamber giving a 11.0:1 compression. Also has giant 2.20 inch intake valve.
To go from a 11:1 to 14:1 you would need a 46cc chamber which wouldn't be possible since you would need to mill around 0.168 off. You would need different pistons ect.
