Trick Flow 440 heads, The Real Deal?

Ahhhh I was curious about the carb on the tf intake. that is just eye opening, you can be leaving a lot on the table by not having the correct intake. Im not an engine builder, but I just didn't expect all off the shelf intakes to be such a restriction to these heads.
What I think is really weird is the intake shootout that was done by frieburger a few years ago. It was bizzare how close the intakes were.
