Which MAF Sensor?

HI there,
Due to the different weights in the valves themselves, I feel any of the following could occur.
First, the spring will not be able to push the valve back under high rpm conditions, resulting in a few things. Possible fatigue of the valve springs or rocker arms.
This may result in a bent valve, bent pushrod, or a broken valve spring.
While we all know that if you break a valve spring, it will not be damaging to the engine, the other 2 possibilities will be.
This is my theory, based on GM engineering guidelines set forth on the 02 LS6 engine vs 01 LS6.
The number I can reference on your cam is the one on the end of the tube, not the cam itself.
Allthebest, c4c5

As someone who has raced and broken valves, I understand what C4C5 is saying, you may not have the "best" combination here. With any "stock" motor, we all have faith that we can run it to the redline and and it will not break. That may be a false sense of security, but if the factory made it, we assume it was right and we should be able to run it hard without failure. Well sometimes things break.
When you start changing components, you may loose that small assumed margin of safety. Maybe redline +400 is no longer safe.
Other brands of cars may have more piston to valve clearance, and can tolerate float. High performance engines usually don't have much clearance because of the high lift cam.
I dropped valves in a 600 hp race motor. Why, because the springs were 10 races old and had lost 20% of their pressure, and I revved it to 7800, not the original plan of 7200. When you are revving to redline and beyond anything can happen.
If you have a warranty, you can smile when it breaks.
