Valve float.....

I saw a posted video a while back of some dude with an ECU that bumped his fuel cut-off to 8000 RPMs(I know that the JWT ECU only raises it to 7200). That seems pretty risky to me.

Does anyone know at what point does the VQ30DE experience valve float? I know that installing thicker rocker-arm springs will help this, but I dont think this guy did that. Also, doesnt the engines "stroke" limit red-line capabilities?

Just trying to educate myself on our engine.
