Taking the already well designed ports that the manufacturer spent thousands of hours designing, modeling, simulating, and testing to get the right balance of intake velocity, flow, and swirl, hogging them out way too big, and then adding a sharp turn on the short side radius right before the valve is about as bad of an idea as I have ever seen.
I get what they are trying to do, but they have nothing to back up their claim with. 7% more power? That's vague. 7% more power where? A before and after dyno plot of multiple runs would be far more convincing.
They likely picked up a little more power in the lower RPM range due to that higher velocity, but I would almost bet there is a loss in high RPM power due to a decrease in total mass flow. Decreasing the cross section right at the radius, right before the intake valve seat will do exactly that, decrease mass flow (and likely increase turbulence).
In fact, if you want to watch a good counter video to this whole idea, I welcome you to watch one of my favorite channels who does a great response to this whole methodology.
