So I was pulling the 2.8 rockers in preparation for mounting on my 3.0 and I found a bit of wear…

Is this normal? If not, can anything be done to restore them?

Need to be replaced. Better to source used good condition factory ones. Stay away from the Chinese aftermarket units. Higher failure rate than stock.

Who sells aftermarket rockers? Didn't think there would be a demand

Available from MTC and Febi for Volvo cars. Both aren’t really good brands at all, but it’s my only option. I called a Volvo dealer to check availability on the updated aluminum rockers p/n 271617, but I was unable to get a solid answer if they were available. And at $46 each, it would be quite steep for a full set.
After removing the valve covers from the original 2.8, I found the rockers had already worn down and eaten the cam. The engine only had 24k miles, so it seems like the original rockers were pretty much trash to begin with…

Not to turn this into an engine oil thread, but is this the type of wear that happens due to lack of zinc (zddp) in modern oils?
I've been running Valvoline VR-1 for that reason, which has higher zinc content. Extremely high levels are apparently bad for the catalytic converter, but I don't believe that VR-1 exceeds the amount of zinc used in conventional oils of the 80's era.
I'm running 20W-50.
