Can the O320 handle 2800 RPM Cruise

Thanks for the input here. I feel safer now dialing it up to 2800 if the need or desire arises.

I have a catto prop and notice no real vibration annoyance. I also have a nice headset that blocks out all of the noise. Other than a very slight vibration of the bottom skin under my feet, I don't really notice much difference between 2500 and 2700. 2800 is no different than 2700 and I would expect 3000 to be the same. I suspect the light weight of catto minimizes vibration issues. I have read posts about uncomfortable flights with FP's due to the RPM's, but I don't really see the issue.

10% overspeed with a 2700rpm redline is 2970rpm.

I have an insufficiently pitched sterba prop on my 150hp O320 and it'll happily turn 2950 in level flight down low. I try to keep it under 2800 as a rule for noise, but I'm not remarkably concerned about seeing 3000rpm.
