I see this thread has gone awry in a hurry, so all I have to offer is some additional info.
First, fully CNC ported refers to the intake and exhaust ports, as well as the combustion chambers being entirely machined with a CNC mill. It does not mean max ported. Even an RPM head could be called CNC ported because of the port entry being CNC gasket matched. They are definitely not fully CNC ported. The Trick Flow big block 240 heads are fully CNC ported, but the 270s are fully CNC ported bigger.
The flow chart sent by TF, says 293 at 600 and 301 at 700. For 190 ccs and a 2.02 valve, that's respectable for a stock replacement head. Exhaust is about 240.
From past experience, Trick Flow won't even sell a bare head until about a year after they are released. They want to build a reputation for the head before they offer them to guys who will modify their work. They don't care if someone makes them better. It's the hacks that they are afraid will ruin the heads reputation before it has been given a real chance.
