This often has more to do with the stroke of the engine than the heads. Having smaller ports in a non-VTEC head helps with low end torque though (because of higher port velocity), but then you run out of flow at higher flow and RPM. This is why an LS-VTEC setup is a nice comprimise. You have the torque from the longer LS stroke, and higher flowing ports (and better cam profiles) from a VTEC head.
