Homogenous would be good starting point for port development

Sonic choke would be more for you to look into on your "high Velocity ports"

As RPM goes up demand in the intake port goes up = high air speed

It will not matter how "developed" a port is min and average cross section will become your limit as the port will go into sonic choke and HP and TQ will suffer

My port is developed as a good Homogenous port with Acceptable air speed for larger CI fast bracket car or high RPM small CI .

BTW. the head with large ports has been proven at making power this is just not some WAG.
