it has been up for debate in the past...
with boost high rpms can twist the stock crank.
naturally aspirated people have raised the rpms without crank problems.
I wouldn't do it,,, but that is just my opinion. especially with any boost or nitrous.

Not sure about valve float. you can get different valve springs and solid lifters with adjustable push rods.
