I should have noted that I'm a relieved owner of an LS3.

Ok, great. Thanks for making that clear. Now I know what to look out for.

I bough an L92 take out that had about 12K on it and it had broken valves. The head of the intake valve was missing completely from the engine i got, and the valve stem was bent and it cracked the valve guide. The top of the piston wasnt too happy either...
