From ZZP's website: ZZ Performance

These work with all stock or aftermarket pushrods, lifters, springs, retainers.
They will work fine with stock springs and pushrods. The only thing I would worry about is if you are running stock springs, and they are high mileage, you might want to replace them so you don't break one.

As for noticing a difference, yes, you will.
