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.
That is the way I've always done it on Chrysler heads. So far the air flow has been pretty good.
