Valve spring tension vs RPM

Does valve spring rate affect RPM and why?

Yes, rate is control and never changes, though spring pressures will

Re: Valve spring tension vs RPM

I went through some of this when we selected the valve springs for my S/S heads.Spring rate and the mass in the spring determine the frequency that the spring will operate at.Its possible to have the correct spring rate but not frequency.That said I leaned heavily on the guys at PAC for the right answer.
