I can comprehend fine thanks. There is a place for smaller ports depending upon the build. You cherry picked one data point to try to make your point, but chose poorly.
For the record I am using some tiny port 413 RV heads on a 440 RV engine I am building. Been told by many that they are junk and wont make any power. Fact is they are the best heads for my application as the engine will never see north of 4500 rpm. It is all about low speed torque and keeping part throttle velocity high trying to get more efficiency.
