Has anyone tried moving the chamber wall away from the Intake valve on that "flat" portion?
Any EVO experts care to weigh in on this?

Marked improvement depends on valve size. I always move a small amount of wall on the exhaust side, as the wall is closest there. ;)

Thanks John, The intake was pretty close at 1.9, I took a little out but I didn't see any
gains. (I probably didn't take enough out) Just curious b/c they flowed a little less than
I expected (like 10 less).

I also un shroud the wall on EVO heads,especialy when bigger valves are used
