Are the rocker bores worn where they ride on the shaft or the tips?

Tips can be pretty easily resurfaced. Worn bores might be a little more complicated and require a re-busing or such.

Search for a recent thread, actually one I started, for a lengthy discussion. I think the title may have been “rocker tip wear” or some such thing.

My machine shop was able to source new shafts. I ended up using some good ones off a different engine. Not sure if new rockers could be found other than NOS.
