They don't have the greatest rep for quality or maintaining spring rate.

You're right at the upper limits of those springs. Aggressive ramp designs makes it even tougher.

How hard were you turning it when valve float occurred?



Well, the issue is that I can't get it to Rev more than 4800, since day one. Sometimes better, but most of the time worse.

Again, I really think that the problem is that the springs were never installed correctly. That is, "incorrect spring height".

I could be wrong, but until I check it myself, that is my theory.
