Worth pulling /6 to "freshen up"?

Cylinder walls look good but there is a bit of a ridge at the top. Not sure if it's worth the machine work to address this.

If I can catch a fingernail on the ridge, I would at least dingle-ball hone it out. And check taper and wear just in case it needs to be bored.

How can I check to see if the head has been shaved already?

Did you CC the chambers? This will help figure out if it's been shaved or not.
