REBUILD! You'll know exactly what you've got. While you are in there, hit some of the other known problem areas such as the rod bolts & IMS. Also, make a few updates. Replace the variocam pads & chain ramps. Replace the valve springs, rebuild the cam followers, and maybe get the heads ported. Get the injectors rebuilt. Add a sump that addresses oil starvation under high-g turns. You'll have a dependable engine that performs better than new. And much better than a used engine.
