If you are refering to these flows, this is is with the stock 2.19 valve and the only thing I did was open the port right by the intake manifold opening. Nothing else was touched.
IF you are refering to the 372 cfm, it is with a larger valve, but I would hesitate to say the port was finished. It was my first attempt to get maximum flow from the EZ and the only EZ port I ever worked before checking on the answer to your question about lower lift flows.
