valve stem height - need some help

I LOL'd you because I was in agreement that valve stem heights (among lots of other things) were far from perfect from the factory.

I still think I would rather have the valve stems all the correct and same heights than reposition the seats for optimal flow. That just doesn't sound right to me, regardless of how respected a porting service might be. "IF" I ever build one in that high end a category, I want valve train geometry to be dead on, even at the expense of additional flow.
