Check to make sure the rockers were installed onto the shafts in the correct order. There are left offset and right offset rockers. It looks like a couple of them might have been reversed. Check to make sure the rocker is centered on the valve tip. If a "left" was installed where a "right" should be, you could get that kind of wear.
Thanks
Your right, I found a partial picture of a 340 rocker assembly, just happens it's showing the rockers I posted that the tips are wearing offset/badly. If I'm looking at this correctly #3 exhaust and #5 intake are lefts, but should be rights?
Where could I find info/pictures on all rockers to check correct L&R orientation? Or is it simply L&R front to back?
Also some rockers are looser than others on shaft, some I can barley wobble others are pretty loose. What's should I look for or is this normal?
