Budget cylinder heads for a 318

For low to midrange torque and throttle response, would 2.020" intake valve's and 190cc intake ports be to big? Is Port velocity important for low end torque and throttle response? I'm not wanting to spin the 318 over 5,500 rpm's and I was thinking that a 3.23 gear ratio would be okay. Am I going in the right direction for what I'm wanting to do?

We have some big name engine builders here and every one of them I've seen quote that larger valves increase power everywhere, so I wouldn't sweat that.
