[2010 SS RS]

Hey guys... I did a search and saw some threads of this happening, but no specific info was really found, if this is a repeat subject I apologize.

I'm just trying to gather up info and have a general discussion on LS3/L92 heads breaking and dropping their Stock Valves. Who else has had or heard of records of this happening ?

It's happened to 2 local guys here in Colorado, and a LS3 camaro over-seas that the owner lives here 1/2 the time in the year. Thats 3 I have personally heard about all happening in the last 6 months. All with LS3 heads, all with stock valves and in mild cammed cars. All breakages happened at low engine load and 2500 or less rpms, and the valve springs were ok.

I know valve springs can break due to harmonic valvetrain noise, can the same be said about these light valves? Just another avenue of thought to think about when it comes to breakage.

Again, just a general discussion, this is not to scare off anyone from modifying their engines. There are literally thousands and thousands of people out there with zero issues, I'm just wondering if this is becoming more common trend to follow here, or if this unfortunately follows under "low percentage & bad luck"
