273 adjustable rockers need refurbish.

I had done a search on here looking for 273 adj rocker mods/info and it led me here. Sometimes I would rather read an old thread rather than start an entire new one.
Informative thread,adj rockers can be used in any combination(hyd vs solid in both pushrods and lifters), didnt know that.
Can I spot face the rocker top with a belt sander? Suggestions?
Hope the OP is getting things ironed out??
