Ralph not being in the room when the heads are being flowed and not owning my own stuff to do it... is there a way to know if the port is quiet by looking at CSA and port velocity? Do I just need to ask the head guy if they were quiet?

How far past max lift would you like to see it "flow well" .050?.0100? more? and by "flow well past" do you mean the CFM should still be increasing or just not backing up a lot? if it just holds the peak CFM from say .350-.500 at a fairly constant CFM but isn't gaining anything or dropping off at all is that okay?

Thanks
