Why in the world would you doubt that guy ? Because your guy could not beat it ?
How do you know there is only one set of Marcellas High Ports out there. I mean, I do not know for a fact that there is, but I believe Scott Brown owns the CNC programs.
If the man says he did not move the valve why would you doubt him ?
Not sure why its so hard to believe.
Mikes E heads went 414cfm.
Thats 134cfm over as cast (280cfm)
High Ports as cast 330cfm.
Johns HPs 459cfm.
A difference of 129 cfm.
Thats a little less that his difference with E heads.
Seems reasonable to me.
Looking at some of those old ,great threads maybe you have a old ax to grind ?
