Procomp /Speedmaster CNC big block heads

Just wondering what peoples opinions are on these heads.
A friend has the 325cc cnc ported ones that run the offset rocker fitted out with decent valves, springs, guides etc.
They are a huge inlet port and he had them flowed at 356cfm at 700 lift on the inlet and 295cfm on the exhaust.
Im thinking the flow isnt that impressive for the size of the port compared to the brodix or trickflow 270cc heads and this may affect how it runs?
comparing max wedge to cnc standard port ? Everything I`ve rerad is about inline w/ the trickflows.
