At what RPM will the stock cam and valves with stock springs begin to float?

I heard some clattering, which I can only assume to be valve float at around 6200 or so. I mistyped in the PowrTuner, and got that!\"NASCAR is an integral part of my life. A part of me died when Dale Earnhardt died.\"

THink it also depends on the age and miles on the car too.
I had fairly new springs and valves (bout 2 yrs old), and got float at 4500 RPM (at ~11 PSI of boost tho)Comment
