It like we have 400 people who smoke, saying we've all been smoking for years, and none of us have gotten cancer, so smoking must be safe.
We know that's just not true. Safe for now, sure, but for how long.
Oh, I was looking at Wikipedia, noticed it said LS3's had hollow stem exhaust valves, just saying. ..

It not difficult to explain, it just seems to be slow to be listened to.

Its more like we have 300ish smokers who feel its safe because they have been told 300ish smokers have been doing it for years. The real story is of the 300ish smokers 250 of them just started smoking and the others are long gone without knowing if they got cancer.
As to the creator of this thread... well he only smokes a few packs a year yet tells you smoking is fine.
Using this list as any indication for success for this build would be a big mistake. Use it for what it is. A collection of members who decided to try something different and see what happens. See you all in 50K miles. Most wont get there and the others will have sold and moved on. To the few who make it I look forward to your results in adding some real information to this build.
Ask Madsen if smoking can kill you. This case doesn't like to be talked about and the blame is shoved all over the place. Anywhere other than the failed valve.

Aside from that there could be 500 smokers in this "list" and it wouldn't mean a thing compared to the overall production numbers for the Z06. The OP can start doing his little happy dance once the list breaks 5000.

LS3s have solid stemmed exhaust valves.
Also, any comparison of running SS valves in a car and a person smoking, and the KNOWN health issues which are directly tied to smoking, including the ill effects of second hand smoke on children and adult, is a stretch, but OK, I'll play along..... Where have we seen an example of one of these cars to suffer a KNOWN issue which was tied to running SS valves?
And BTW, this procedure of using SS valves in these cars was first done by LG Motorsports back in late 2005, so it has been going on for around 9 years in these cars, but we don't see all of the reports of predicted ill effect. Furthermore, as already mentioned, several other shops aside from LGM, and several other cylinder head professionals recommend and prefer this approach as well, due to the expensive and sudden failures observed in the stock LS7 exhaust valves.

As for "smoking", well, I can show you several examples where smoking cost someone their health. But no examples reported of running SS valves in a LS7 where it caused any known practical ill effect.
Now if you wanted to make a comparison, well, in my opinion, sticking with the stock exhaust valves is like knowing that you are holding a ticking time bomb, dump, and making no effort to do anything about it.
Knowing that there is something inside my engine liable to result in suddenly putting a hole into my engine block, even if I'm just backing the car out of a parking lot http://forums.corvetteforum.com/c6-p...post1582728491, and doing nothing about it, is an approach which is unacceptable to me.
As for Madsen, a case that some in here like to harp on, well, not changing out his guides at the same time that his valves were changed, probably had a lot to do with his failure. http://forums.corvetteforum.com/c6-z...post1584796647
And BTW, the thread has surpassed the "2011 Carbon Edition check in" sticky in views.

Are these 2 builds going to have a problem with Titanium/Molybdenum valves?

So true ramairws6. So true.
In terms of views, we are about to overtake the "2011 Carbon Edition check in" sticky thread, and that thread had a 445 day, or 1 year, 2 months, 17 day, "head start", no pun intended, on this one.
The listing is heading into 375 CF members, and from there on into 400, and the "landmark" number of "427" CF members.
When it hits 427 CF members, it will be both an ironic and somewhat of a historic point indeed.
I expect the listing to grow, and one other thing which you have possibly noticed.
As the number of forum members who have taken this step has increased, the incidence of failure reports due to dropped exhaust valves in here has decreased.
And ramairws6 you are of course as always, free to interpret that at your own discretion.

Richard at WCCH did 175 LS7 heads last year alone, almost all with SS valves. So I would imagine it would be save to conclude He's done over 1000 in total so far. We know our reported SS heads in your thread is but a small fraction of those done across the nation (and CANADA !!)

LS3 has hollow intake valves.
Corvette engines with hollow-sodium filled exhaust valves: LT4, LS6, LS7, LS9, and the Gen V LT1. FWIW each and every aforementioned exhaust valve is different in diameter, length, wall thickness, weight, and subjected to different lifts, ramp rates, etc.

I think the Wiki page in question was non-specific ("hollow stem valves"); it should be corrected but an official link is difficult to pin down this late in the game.

First it was the number of people that could be conned into putting tractor valves into their LS7 that proved your intellectually incurious hypothesis correct; now it is the number of thread views. I'm am literally LOL here

Ahh Quick.... He never fails to make me chuckle. Meaningless drama threads always get more views and posts than meaningful ones. Welcome to the internet. We see this example every day on this forum. Shops building Z06's putting down 8's get a few hundred views and maybe 20 replies. Troll threads like these... well... I think the point goes without saying.
Most of those views along with posts belong to Quick and Howie anyhow.

I have heard that the rule of thumb is half of the total lifter (cup/plunger) travel. That seems to make sense, at least to this layman.
However, I'd imagine there are probably situations that fall outside of that for various reasons so it probably wouldn't be written in stone.

I see. So you don't actually "know" diddly squat.
But you have "heard" this and that, "understand", sometimes "vaguely", and "guess" this and that as well. Sorry, but I'm afraid that I'm going to have to forgo any "advice" I see from you from here on in, as it does not seem to have any actual practical experience behind it.

You have Me and Ricky on your Ignore list and you claim to miss little gems. Well I have to believe you are disingenuous (euphemism here) to say the least. You, me, Ricky and everyone else on this forum knows you read every single word of what we say. To deny this is simple ********.
You want to start counting how many posts you make in some of these threads compared to me. Pick and choose ……… hypocritical
I'm sure you won't respond to this until someone else quotes it …….. Hahahahaahahaahahaaa
