How many days is the car out of service for the same package as the OP in the other thread? I'm up in NorCal and could drive down to get the work done, but wondering how long it would take.
What is the price of the 'reliability package'? Is this the equivalent of the WCCH LS7 Stage2 package? Any milling done?

Charlie, I would like to Thank You for posting up this additional information, and for answering my questions in the other thread. It is much appreciated. Your the first vendor that I can recall has provided this much info on the topic.
Others have commented here and there, but most( not all) of the feedback I hear is 3rd party from some forum members here, who quite honestly I don't trust, and can you really blame someone for not trusting a total stranger on the internet?
Being a professional shop and vendor here, I value and respect your opinion
You have helped convince me this is a large wide-spread problem, and have provided at least general numbers to back that up ( you said 3-4 sets of heads a month I think you are seeing Guide Wear) and you've seen over a dozen blown LS7.
In your professional opinion... So for my car, an 07 with 25k on it, bone stock street driven (maybe 1 track event a year) I should have the heads done,, I realize of course you cant give me the odds or % chance of something happening, but based off what you know today. The over dozen motors you've seen blow , those are not just tracked cars, youve seen a lot of street driven ones as well correct?
In other words, if you were in my shoes, would you do it? Yes I assume?
if you were closer to me, I'd be calling you to set up an appointment, just based off your willingness and time you've shared here. You have great pricing. ...although by the time I ship you the heads and insure them, and have them pulled and reinstalled it will be cheaper to do local here I imagine.
Hell, maybe I could take a drive from IL to CA, but yet again, I'd be afraid I;ll drop a valve now

I noticed you list a trunnion upgrade as part of the service, and I'm not trying to start a pissing contest about doing it or not, but, do you believe or feel that the free play in the factory rocker contributes to the 'excessive' guide wear, is a major factor in the wear or is doing so just a preventive nature thing to shore up a weak spot?
I ask simply because of the varying opinions of other vendors as to the need. I am not seeking a desertion

trading in your "white knight" status? 
you know i am just giving you crap and its all in fun. its good to see the op's post on this and it continues to confirm the issue and may very well prevent someone from dropping a valve by having the head work done or at least checking their guides.

i like the upgrade because it fully cages the needles and minimizes, if not eliminates the "spilling out" factor.

oh come on now, GM said it's 08 to 11 cars. yours is an 07 and isnt affected. i am sure you will not be in the 1% failure rate of the 06 to 07's. the op is just out to make money off the problem just like carlos was and some of the others that were accused of it. its all internet hysteria. GM will make good on it as long as you are stock. trading in your "white knight" status?
you know i am just giving you crap and its all in fun. its good to see the op's post on this and it continues to confirm the issue and may very well prevent someone from dropping a valve by having the head work done or at least checking their guides.

it's all good... I've got my extra thick flame suit on now and I am sure I will get hazed by a few others for being stubborn and taking a long time to be convinced. I just wanted at least one vendor like RPM did here to give us info as he did. 
thank you. i don't frequent the site as mush as i should but will try and add more in the future
I know what you mean, although there is a lot of good advice on these forums, just need to filter it
yes, as the cars gain miles and get near end of warranty we are seeing many owners modding or taking preventive measures.
Mostly we see the valve head failure on cars that have been modified or tracked - about 80%. However, I recently finished an '06 from Utah with 36k on the clock. all street miles never raced - after the valve let loose the only re-usable parts were valve covers.
I'd do it - in fact i did on my own car immediately
drive out - i'll put you up in a nice hotel - but, the gas would be a killer

and what you said about 80% being modded or tracked cars, that fits I think with what we've seen here on the forum.Yea I imagine the gas would be brutal
in fact between you in CA and me in IL, we have some of the highest gas prices in the country.I have not totally ruled out yet shipping my heads to them
I'll need to look at insurance/shipping cost. then decide if I want to pull the heads myself , which I certainly can, however I might just have it done for me to save time and hassle .

Listen, even GM is admitting that examples of this problem can be expected to show up in 2008, 2009, 2010, and 2011 cars.
If that ain't "widespread" well then I don't know what is.
So if even the manufacturer himself, is coming right out and saying that this matter could show up in an '08, '09, '10 or '11 car, and the manufacturer does not even give the VIN numbers of the cars which might be involved, but rather says that they can "likely" be identified by unusual valve train noise, then at this point, only a complete fool would try and argue that it's not "widespread".
So no, I would not even worry about "changing positions" and the potential repercussions in behind doing so.
Charlie has added information that you didn't have before, and he has done so right in the wake of GM's admission that this matter has been going on from 2008, 2009, 2010 and 2011......and there are those who strongly believe, and there is evidence, that it was going on even before then.
If you should decide to get your heads done, in behind the information that Charlie has given you, coupled with the recent events of the last few days coming from GM's own mouth, you don't owe ANYONE in here, not a damn one of us, an explanation.
