Valve train problems on a C6 Z06 corvette LS7, know of any forums?

[Ducati32]

I'm putting together a list of people that have had valve problems with a low milage corvette Z06. These problems are common in about 10% of production and almost always cause catastrophic engine failure. GM is telling there customers that it's an isolated occurrence most likely resulting from abuse and therefore not covered under warranty (Est $25,000 repair). In an attempt to prove GM wrong some of us are joining together to create a list of names and occurrences.

I need to get the word out on as many Forums, chartrooms and group meets so can anyone tell me of the most popular places to find corvette enthusiasts?
