Ya Know...I'm leaning toward the Cam Lobes myself. Reason being- Did you use an Oil with Adequate Zinc?? Not trying to advertise, but I've seen a couple of 2.2's and at least 1 small block with wiped out lobes because of the newer 'ecologically sound' oils that don't have enough Zinc in them. I run Rotella in my cars now- save for my Stratus which has a factory roller cam.
Real important in this day and age to know what the ^($*&% they are doing for the 'enviroment'.
