Matching up the flow bench numbers implies you care about having the same amount of pressure drop across the valves as across the primary tubes.

I don't see any reason to try matching those values. Maybe it'd be more worthwhile to match velocity. None of your parts are going to flow that cfm on the car anyways.

Personally I'll take the least restrictive part available anywhere I can get it on the system until there is a penalty in torque loss or something.
