I am sorry Mr. Z06 505 you must have missed the memo, it has already been decided on this forum there are no sodium valve stem issues, you must be mistaken. It was probably related to the headers, or did you have your exhaust flaps closed during this event, I heard the back pressure could cause these things to happen...
So please don't continue with the sky is falling posts and doctored photos, we know what your up too.

Please stop defending the engines.Its a fact that the ls7 is very delicate and that a huge proportion of them have blown up very prematurely.When i bought my 07 two years ago and i brought it in to the dealer for an oil change they kept the car and rebuilt the whole motor.Had i driven it a little while longer it would have also exploded.The ls7 makes tons of power but is very delicate.Rocker arms ,retainers,whatever it is, something in the vakvetrain is weak, and causes them to let go.Doesnt take away from the fact that the z06 is an engineering marvel ,is the best bang for the buck ,and moves like hell.The engine however is not reliable.
Exactly what is a "huge proportion"?

The fact is that no one in here can deny that 24,000 track miles on one motor, stock, modded, what have you, is impressive.
24,000 track miles, depending on how hard he was driving it, could work out to an equal or greater amount of overall wear and tear as Jimman's 150 some odd thousand highway miles.
24,000 track miles, running ***** out, out of a total of 34,500 miles is a lot to ask for from any engine.

He only put about 10,000 street miles on that engine since he bought the car back in 2006. The rest of it's life was spent on the track.
Some of us are looking at this entirely the wrong way.
Instead of getting up in arms about why this one popped, we ought to be doing just the opposite and asking ourselves how come this one lived as long as it did considering the use put on it.
For example, I for one, want to know what kind of motor oil he was running in it. How frequent his oil changes were, or any other valuable information that would help me understand how he was able to get that kind of use out of it.
Reviewing his prior posts, the only way he was not at a track event, was if they weren't having one or if he was sick.

I had around 7K track miles on mine when it let go. I would be very content to get 3 times that on this new motor.
Maybe I need to do MORE track days to make it last longer !!

I don't think that there are lot of motors of any type which can give you 24,000 track miles before they crap out.That's like running the 24 hours of Lemans about 8 times on one motor.
$#!*, with that kind of success, this guy ought to be selling tunes.

The tune, headers and dry sump were done several years ago. The valve broke 2 weeks ago. I guess it's possible I caused the problem. It's also possible I did not. No one will ever know for sure.
I'm not crying...just sharing. Everyone is entitled to their own conclusion.

It may or may not have been his headers and/or his tune, who knows? But that issue is practically moot. Indeed it is completely moot. It may not have been his tune which ultimately took out his engine, it may have been just the sheer number of track miles.

I have lift in garage and I am retired, so complete maintenance routine between events although not much related to the engine other than air filter cleaning and checking for abnormalities.
I drove harder and harder with each subsequent season. I drove it like I stole it the last several years.
You are right that since purchasing the car, my life has revolved around tracking events.
I missed events only when it rained. I have driven sick, especially at MidOhio through "Madness"

Royal Purple XPR 20W-50 changed once per year. I bought it by the 5 gallon jug.

Not accusing you of stating that you never tracked it. And yes, reviewing just a few of your prior posts, it is quite obvious that you are at home on the track.
I was just trying to get an idea of how much it was able to endure in terms of track duty before it finally failed.
I appreciate your response.
24,000 track miles is pretty impressive.
24,000 track miles/34,500 total miles represents about 70% track duty and 30% street duty.

If anything , I think this DIS proves the sky is falling crowd
In fact , any little shred of doubt that some have out there , take a look at this thread and how many TRACK miles this motor saw before it popped.Some folks just expect a factory motor to live forever , and when it doesn't they place blame. Those folks ought to spend some time with any professional race team and see how things work a bit better.
I have even more faith in the LS7 after reading this thread

Does anyone know about the antiwear additive package in this particular motor oil?
24,000 track miles with no engine maintenance aside from changing the oil and filters, is an outstanding feat.

I apologize if i'm going a little off topic here.
Is it safe to say that a stock block LS7 with a medium sized cam, and perfectly set up valvetrain from a reputable sponsor will probably be more reliable? Maybe set the rev limiter a little lower and put a nice conservative tune on it.
I would probably only use the car as a fun street toy. maybe get into tracking it eventually but nothing serious.

Apparently the motors are designed to drive the car, but don't much like being "driven" by the car.
Of course RPM matching and good clutch work can reduce this effect.

Burning Brakes
I don't know this to be true of cars, but with motorbikes it's the reverse torque applied to the engine when downshifting or engine braking when coming off the gas at high rpm.

Of course RPM matching and good clutch work can reduce this effect.

Hopefully you're not replacing the entire block... but it's still a major deal. Really, you want to avoid any contact altogether so even SS valves are not really a "fix" in the sence that you're not preventing the problem from happening, but rather trying to mitigate the effects once it does happen.
I think the question still remains: what, exactly, is happening? Do after-market heads have any increase in longevity over OEM with people who've replaced their valves/guides?
