Jack,
Generally a larger valve is needed when the RPM's go up and a 2.02 valve doesnt really help til you get up to 7000 or higher. And as for flow they actually loose flow in the low lifts where most people really need it up to .500 lift. So the small valves are the better choice and this is why I use them as I dont turn my engines over 6500 RPMs anyway. And most of the time they only see 6000 RPMs.
