Help with Valvesprings and valve float. Noob

My philosophy when it comes to dealing with valvetrain stability problems with hyd cams is simple.......
Use a spring that is absolutely positively “enough” to allow the motor to achieve the desired rpm.
If the motor still doesn’t reach the desired rpm, you need a different cam(and or lifters).
I’ve seen this situation play out countless times.

The root cause of the inability to turn high rpm is linked to how well the lifters resist bleed down.
This is why you can do nothing but swap out the hyd lifters for solids and pick up 1000rpm(if you have enough spring).
Eliminate the collapsing lifters from the valvetrain, and you eliminate the problem.

This is the case even in something like an NHRA stock eliminator motor running the OE rockers and a cam with OE lift.

Another approach is to use a cam with lobes that are slower/less aggressive, that are less dependent on the bleed rate of the lifter being optimum.
