Ya know, every time "we" get an enhancement, "we" have to go running back to the dyno to figure out just how "we" can exploit it.
Well, maybe it's time for the Tech Dept. to give an un-enhancement a try. Put a "valve spring rule" in place (200# sounds good) and watch how fast "we" go about figuring out how to make it work. I'll bet it will fix the AHFS in a hurry too!
If ya think about, it's kinda funny how a rule change can have the same effect but in a different direction. Instead of giving us roller lifters that "we" will spend loads of time and money figuring out, take away the big valve spring pressures that let us over rev our "Stock" engines and watch how quickly "we" will figure it out.
And maybe, "we" won't have to spend stupid money on aftermarket rods, cranks and blocks that "we" can't get anyway.

Rules are a funny thing!
