There is no doubt you can gain lift and duration at different points in the curve, but, that's no different than grinding it into the cam.
With that being said, there is NO WAY you are going to be able to open the valve any farther than max lift...and that's what we are talking about here.
Now, without a doubt you can make the engine much happier up top in the rpm range by correcting the valve train geometry and I am not talking about rocker geo. I am talking about the entire valvetrain.
At the end of the day who cares what the valve does when it leaves the seat...as long as it does not open any further than what the spec says is the max. where ever that just happens to happen in the entire curve

Because it is not maximum lift that matters. It is how fast you accelerate the valve, and how much area under the curve you generate.
