Mine had about 500 hours with half of that running a whipple . I had a valve seat let go, and I think that is the problem you may have heard about. Not ideal heads for supercharger application. They are great as they are designed with stock setup, but not setup for a supercharger. I rebuilt it using aluminum heads, and have about 50 trouble free hours on it, and expect many more. As Griff stated, they like to use oil, but mine uses less using mobile-1 15-50 as well.
