I'm loving this thread
If I only had that time to just dedicate myself on this topic, things would be neat

The intake valves don't flow enough to enable high revs. There is a very limited space for both increasing the lift and/or intake valve diameter. The bore is small for fitting big valves to the area available. The stroke is long resulting in high velocity that will choke the flow at high revs. Look at VAC results. They say springs can handle 10k. So the problem is the lack of valve diameter/lift. N54 is not a high revving engine and will not be one.
Personally, I like to have the power readily available without the need to get to high rpm. Before the modern forced induction times high revving engines were the way to go. Now we have turbos that can make power at lower revs. Great.
