Just don't misinform people on how to deal with problems if you don't know the facts.
Not sure if serious....

The fact is there is a flaw with something in the stock GM heads. So why continue to use them when there is a "fix" that has had zero failures?

There has been failures with SS valves and reported guide wear regarding "the fix"....do you still think its a fix?

"The Fix" involved taking a set of stock LS7 cylinder heads, changing the guides to manganese bronze, changing the exhaust valves to solid stemmed stainless, polishing the intake valves and using a suitable valve spring for the setup. That's it.

Anything else, is not what is referred to in here as "The Fix".

There has been one report of valve failure in a car said to have had "The Fix" in here.

A case where a bent valve stem with an absent valve head, suggestive of piston to valve contact was pictured.

There has been no car in here with what is known as "The Fix", to show out of spec guides.

Ummm last time I checked, there weren't any issues of any LS7s with a set of heads from Richard while the long list of Z owners who have prematurely blown their stock motors continue to grow. It's up to him in the end. He did say he had a set of long tubes on the car so its already modded. Who is to say he won't throw on more bolt ons in the future or a bigger cam/tune? There goes your beloved warranty out the door!!

Actually there are but they get covered up, excused, or simply not spoken of. One member had a Rev exhaust valve go bad (didn't break), another had some excessive guide wear barely inside the service limit (wiggle test).

^this...."the fix" is not a solution to the problem IMO..it is essentially a bandaid that is harder to take off for now.

Of course you choose to ignore how badly worn his guides were with factory parts after roughly the same mileage, but I doubt you ever bothered to talk to him about that.

I think that so far it is safe to say that the WCCH head redo has a very small number of problems particularly compared to OEM heads.

I don't think anything in a high hp application is fool proof but I think the number of WCCH problems is small enough to earn them the favorites choice at this time.

Is it absolutely the right choice......Who knows.

I am a belt and suspenders kind of guy and would probably change the rpm limiter in the tune to 6600 rpm, but than that is just me being conservative.

Ricky, is that indicative of valve float?

You know, when you listen to all of that talk against "The Fix" on the wake of all of the failed LS7s on here, it just makes you shake your head in amazement.

We have yet another story of a failed LS7, just today.

No need to argue with naysayers about what has and what has not worked.

And "The Fix", continues to work.

You continue to engage in sophistry. How can you possibly make the connection in the failure discussed above and "The Fix"??

Not a shred of evidence of what caused the failure as described.

Are you Clairvoyant?

Continuation of intellectual dishonesty. You need to get off the forum 24/7 and drive your car more often..

Everyone of these "fix threads" get ridiculous. There will always be spectators (let it happen people) and players (make it happen people). The two sides never agree.
