Hey Chris after reading your pearls of wisdom, I checked out Comp Cam's site. Do you think their cast steel rockers will have the same wear problems? I suspect they may since there is a version that is labeled "rebuildable". I suspect the problem is similar with Chevy motors too, although the 1.6 ratio and 1.7 ratio rockers probably add more stress to the pivot bearings than a 1.5 ratio does.

I'll throw this question up at Chevy talk, though this point has never come up there
