Budget cylinder heads for a 318

ANY new head should be gone over. Even the best of them. It's par for the course and if you don't do it, you'll regret it. AFR doesn't make Mopar heads to my knowledge. The best Mopar heads available now are the Trick Flows, but even those will need to be inspected. There's no way in the world I'd spend that kind of money and not have them checked over.
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?
