Do you think that they (and everyone else) do that, because... oh, say... the significantly increased heat from a turbo setup relative to N/A?

And wasn't one of the two SS valve issues on a set of WCCH heads? Assuming it were, would it change WCCH's reputation in any way [no], or would people assume there is something else more likely to cause failure [yes]?

I asked the same questions and essentially am told that guide measurements aren't necessary with the "fix' because of the confidence everyone has in it because there haven't been enough failures.

At least one has failed, which apparently had excessively worn stock guides in it, which suggests that guide wear causes valve breakage even with solid valves. With that fact, I can't imagine why more of those owners aren't interested in having their guides measured to make sure they're staying in spec. It's not like worn bronze guides are going to grab the valve before it drops and say, "whoah there buddy stay up here."

On your second point, the point of these forums is for owners to combine and share information and make everyone's experience better. When there are secrets, they don't help anyone and stating that you have been given an expert opinion, "just trust me," is meaningless without background information.

I understand if someone doesn't feel they should name names, but if that's the case then you might as well not share the information because it carries no weight.

You gave all the reasons I would respond to.

1 failure? Thats it? In all the years they have been running it? Hardly a reason for alarm and really not worth even mentioning it to make a case against a Katech build with OEM valves. How about some NA cars? Do you know of any failures with any of those builds? An honest question, I don't know of any.

We know failures happen for many different reasons. Who knows the conditions of how the linked car failed.

I never stated Solid Inconel Exhaust Valves are bad in every situation. I have many cars and many builds running SS exhaust valves.

I said I wouldn't do it in a NA LS7. Many things are changed in that TT Air Attack build. Trust me I know because I have spoken with Jason at length about it and it is something I was thinking on doing.

Closed for review based on apparent conflicts with the rules.

There are issues, some more serious than others, in this thread and another companion thread ...

http://forums.corvetteforum.com/c6-z...weeks-wth.html

The companion thread was started by someone who had a complaint after dealing with two vendors -- one selling parts and the other installing the parts.

First off, the rules allow and we encourage the posting of a factual account of any dispute or bad experience with a vendor after a reasonable effort has been made to resolve the issue offline:

http://forums.corvetteforum.com/foru...-disputes.html

Such posts should be made in the Transactions Feedback section and I'll end up moving the above-referenced thread posted by the customer to that section.

Another issue involves hijacking a thread to take it away from the thrust of the original post and that seems to have been more prevalent in this thread, although it also occurred to an extent in the companion thread, including taking the thread into presidential politics.

More importantly, however, this thread and the other is in conflict with site's vendor rules which prohibit one vendor from directly or indirectly commenting on the products or services of another vendor.

Those are long-standing rules designed to combat the so-called "vendor wars" that erupt periodically.

In this instance, it appears we have one vendor who supplied parts and another vendor who did an install. When something goes wrong in a situation like that, it's easy to start finger-pointing and blame-shifting. That is an exercise which just raises everybody's blood pressure without addressing the core issue -- figuring out what went wrong with a customer's car and getting it fixed in a way that it will stay fixed.

I'll discuss that privately with the vendors involved and will invite them to work together offline for the benefit of their mutual customer rather than slinging arrows online for their own benefit.

I'll also ask the vendors to report to me the end result so I can update this thread.
