Valve springs for howards cams

nm
using the larger lifter does not require a steeper ramp
in fact you can use a not so steep ramp and get the same place
it's the radius of the lifter and using more radius that makes the difference
for example

udharold used exactly the same polydines and factors/ parameters for both the Lunati chevy and mopar cams, same accelerations
He used far fewer polydines for the comp xe versions as few as 4 for the shorter symetrical lobes- Ultradyne lobes are somewhere in between
That's why the Lunati lobes are quieter
