Does anyone actually have the GM Bullentin number stating that they have an issue with their valves? I have spoken to the dealership and they need this bullentin number. I Had to replace my blown motor due to a bad valve. Thanks in advance....I am looking for the article where GM came out and stated that they have an issue with the z06 valves...

I understand what you are trying to say and I also understand what a form letter is (even if you are trying now to says its a "form response")
Bottom line is that I have sent 7 distinctly different emails (not form letters) and have gotten 7 distinctly different replies (not from letters).
The responses may not be what you would like or accept. But for now I don't know what else I could expect. I will be getting a personal call from a district manager. I will plead my case and make my requests. I reserve the right to make my final judgement of this issue until I have persued all avenues of redress or until GM makes another announcement.
I reccomend you do the same
GO GM !!!

1 : a letter on a subject of frequent recurrence that can be sent to different people without essential change except in the address
2 : a letter for mass circulation that is printed in many copies and has a very general salutation
This is exactly what you have been receiving. I don't really know what else to tell you. It's almost comical how we seem to be speaking different languages.
A real solution would be a TSB or other solution where owners are notified. What you fail to realize is GM is on the hook to you legally since they have admitted to bad valve guides already. They are just trying to make you go away and not service all owners. Heck they still haven't even gone on record that if they find something they will fix it for you! (Form letters)

A form letter (I said response also since that's what you will get over the phone which I see you already jumped the gun and are talking about that) per Webster dictionary:
1 : a letter on a subject of frequent recurrence that can be sent to different people without essential change except in the address
2 : a letter for mass circulation that is printed in many copies and has a very general salutation

And I do understand that GM may have a legal obligation to me. I am after all asking for recourse to this issue even though I am currently out of warranty.
The difference is I am willing to give them time and the benefit of the doubt. I am addressing the problem through the channels they have provided. I do not see them turning a deaf ear to me. And nobody knows what actions they may take in the near future.

Before installing the new heads also have them check the valve guide to valve seat runout, which I doubt the dealer service tech will be able to do. Better yet, request and pay them to send the heads out to a local auto machine shop that the dealer uses for a complete check with measurements.

No, not necessarily factory warranty. Any warranty.
I'm not following you here. Please explain. What doesn't, in your mind, have any bearing on a 15K mile engine?

Thanks. I'll call this weekend. I just transferred my job to McKinney so I will be commuting there from Lake Texoma daily (that way I get to 'live' at home instead of having to live in the townhouse during the week. I hated not being able to 'come home' during week days when I worked in Arlington. They are sorta out of the way now at this point. My car stays in my shop at home (outside Pottsboro near the lake) so it's much more difficult to get it to Grapevine unless I drive it to work one day.....but Grapevine is still quiet far away from McKinney or the lake area.
I will try to call you on Saturday....what's the best time of day for you?
Tim
Add: I forgot which area your in....northeast of Lewisville, correct?

If the dealer wasn't willing to send the heads out to a local machine shop for inspection and measurements, then I would request that they allow the local machine shop to make the inspections and measurements at the dealership at my expense.

One of the questions I wondered is: Suppose they find this issue in my LS7. What then, they replace the heads.....they said was corrected in 02/2011...?? And find out that another guys (Billyjo username) has his 2011 heads checked and out of tolerance....his engine was built several months AFTER the supposed fix.....
I am in the same process.....my next step is to get my car diagnosed in the "past 30 days" so GMCS will proceed with my case number, as I have NEVER made complaints to dealer regarding engine noise.
But after having listened to (Billyjo's) engine recording , my 2010 sounds EXACTLY like his does in the recording.
So, are/will they replace heads with the same which created the condition to begin with? I'll be glad when my warranty is done. Mine is going to a specialty shop when the warranty expires and becomes "my dime".

Also the GM rep told me the reason it took so long to get the new heads was because the first order the dealer placed had to be cancelled and a different part number used. I'm going to try and find more out about that the next time I talk to her. I didn't think anything about it when I talked to her but after seeing the new heads were bare and the tech is installing all new parts I wonder if there isn't more to that story.

I wondered the same thing and when I asked the dealership if the heads were going to be checked prior to installation their response was "these heads have been checked on a multitude of levels".

I want my original engine though. This car willbe one of 'life-long' toys, especially aftert I retire in many moons. I want this car to be one of my past time hobbies after retirement.
There will NOT be any more 427 Vettes and I wanted one since I was a kid. My family understands this too. None of my family will touch this car b/c they know I like it.

Thank you sir I have concluded "what is the point" if they replace with the SAME parts which created this issue. I might as well let it go 'boom' and let replace the whole dam engine.

Again, I fully understand. So you are saying you have received the same 7 Form Letters that I have....right?
And I do understand that GM may have a legal obligation to me. I am after all asking for recourse to this issue even though I am currently out of warranty.
The difference is I am willing to give them time and the benefit of the doubt. I am addressing the problem through the channels they have provided. I do not see them turning a deaf ear to me. And nobody knows what actions they may take in the near future.

I even tried to go so far as to keep my original heads from GM but it was a no go. Anyone that knows anything about originality can look at my car now and see the heads don't have the correct part number on them. I'm not at all happy about this and I will keep on the look out for a set of heads with the correct numbers to buy and eventually have them installed.
I think this all stems to the fact that my dad has owned an original 67 427 car for the last 36 years and has never changed a thing on it. I know it was one of the reasons I bought the car I have now, because it has a 427 in it.

Right. So me who has been correct since 2008 is a troll but DH is a wonderful member with invaluable contributions. Keep putting your head in the sand that's how GM likes it.

I understand completely where you're coming from, many people here don't care. Even a lot of people that I talk to say why do you care, you're car has a warranty. But I myself like you want my car to be all original.
