Trick Flow heads

Anybody have any experience with these heads? Specifically, whether or not they have an exhaust crossover so I can keep my EGR? I emailed then called Trick Flow and got conflicting answers. Also, for my application, a 305 TPI, (Save it. I'm not going 350/383 at this point in time.
), my choices are these or World Products S/R's. From what I've been able to find out so far, the Trick Flows flow much better and would have the weight saving advantage of aluminum, compression advantage notwithstanding. Yes? No? Why? Thanks!

Re: Trick Flow heads
Yes they do. I ran them on my car with the EGR. Can't remember if they had to be drilled to activate the exhaust gas crossover or not. I know it had to be done on the Darts I'm now using. But the bottom line is yes.
Update. I just checked the picture in the link and the hole is there for the egr.
