Head Choices - With Domed Pistons

so the link I posted (posting again) doesn't have values for the fully ported X head, I have done some searching but can't seem to find numbers, found plenty of references to the comparisons of the j heads though. Am I missing a thread? Anybody have the X numbers? Playing around with some theorectical numbers what ballpark my engine may produce in horsepower, one of the cool things you can see is what some of the differences do for the overall impact, head CFM really kicks it. While I may not ever build another engine its been good looking at some of these things again and some for the first time with more thought. I am going to take a look at my 351 in my Mustang when I get done messing around with this 360.
