Should be is not the same as IS.  None of these after market heads  ever 
appear to be flow benched by the people who make them.

I dunno  if anyone mentioned that the head is a major limiting factor

The crossflow head should be a major improvement over  the stock head
and should work well with hotter cams and such.
It would  almost certainly make it easier to approach the magic 100HP
per liter  mark.
