The names are hyperlinked and thus far there are 130.
If you click on a name, it should lead you to his post where he describes the use of SS valves.
If it leads you back into this thread, well then they posted in it and a trip through the thread will review their having checked in that they are using stainless valves
A few, if the cars were done by Quality Motorsports or Carlos (MyHardtop) had anything to do with them, well then I know they have SS valves in them. You may find 3 or 4 of those in the listing as well.

As I added Undy before his car was put back together, I will add you as well.

Yes, it is.
I figure that there are at least 150 members in here who have switched to solid stainless valves, and possibly as many as 200.
The thread serves the purpose of allowing those on the fence to see that there are more than just a handful of members in here running them, and like it's companion thread, it shows that this has been in practice for some time.
It also, more than anything allows them to see how the method and thinking has evolved.
An interesting tidbit, is that when these were first being done, Carlos was advocating using the stock springs with the heavier valves.
This thread is from 3 years ago.
It is amazing how far people have come in their thinking on how best to manage this issue, and how things have evolved.

In spite of this way of thinking, I found no instances of valve float and catastrophic failure describe in any of the cars I was able to find where it was obvious from prior postings that the poster had him do the work using those stock springs.

Yes, this theory has been tested and it works just fine. When ever we disassembly the heads, we check all conditions of your springs and make suggestions if necessary.
My advise, install new GM springs if not taking the cam route. That way you know you have new/fresh set of springs and new exhaust valves and miles and miles of worry free driving.
To do the SS Exhaust valve job only with full inspection and complete cleaning is $570. Add $135 for new GM springs with valve lap job set pressures and with new seals.
Thanks,
Carlos

Dual springs on a stock cammed car will NOT be ideal.
Tuning may or may be necessary on a BONE STOCK Z...my gut feel is that yes, it will require a tune. Power comes from the heads, and if such component has been enhanced, then perhaps a good tune will bring it all together nicely.

I only put that in there to show how things have evolved since that was written 3 years ago.
Now, nobody would dream of using the stock springs if they were running a heavier SS valve.
This is also part of the reason why I explained in another post, that eventually some mishaps are liable to be seen, because of the variability in how SS setups have been done.
When that was written, some were not even changing guides, nor routinely checking stem to guide clearance.
They were just swapping valves and keeping the springs that the car rode in on. At best, getting a new set of stock springs.
Now, I doubt anyone would do that.

Yes, thanks for that tidbit.
It was the PSI-LS 1511 valve spring.
I recall Rock discussing it a few posts back, with regard to that article.

Get ready to put me on your new list Ricky. This is the second and I hope last list of yours I will adorn.
Install is scheduled for Feb. 1 at Cunningham Motor Sports.
(just have to get through one more track day before that)

Sign me up, WCCH ported and Milled factory LS7 heads with SS exh valves and bronze guides. Vengeance racing installed the heads over 12K hard miles ago with Big Cam, clutch, and full exhaust. No Smoke at start up and Quiet valve train. Car runs great

Except, are you still going to be able to get those pics you spoke of on Friday?
You are signed up, and I added you to the listing.
I have to say, it does feel good to be in such good company.
Guys like yourself, running these big cams long and hard, and not even so much as a hiccup for you. Thanks for posting up, and your mileage, is more than a lot of folks in here, calling this a "band aid", will rack up in 3-4 years time.
Lot to be said for having confidence in your equipment to hold up when you need it.
