What is the best head for a small block.

Does anyone know if the Victor heads are any good? Why aren't we seeing more engines built with Victor heads?
All along, Trick Flow has billed their new small block head as a bolt on replacement, even specifying on the pamphlet they were handing out that it was not intended to be an all out racing head, so I think they will do well in the intended market IF they have good quality out of the box.
I was also looking at how much material there is around the pushrod holes on the Trick Flow. Interesting.
