you can always remove the jets from the intake, direct them into a container, and actually test the effective throughput of different valve duties. this is exactly what i plan to do with my system.
just keep in mind they will be slightly reduced when the jets must discharge into a pressurized intake pipe instead of ambient air--ie true flow rate will be lower than tested when running high boost. luckily the high rail pressure of the hfs5 pump will minimize this effect.
