commando's vs. eddie rpm's

This is a great subject,there has been alot of debate about this in the pontiac community as well and alot of research/testing.It always seems an even split between those voting for bigger or smaller,I have to admit I tend to go for velocity over volume when I do any port work and I manage to get some pretty good power with smallish heads.I admit Im not reffering to absolute max power/rpm but for the street I love to have the response and the power.
