Flywheel service limitations.

1965 Barracuda, 225 /6 904 conversion to an A833 4S.
I have in front of me my 1965 Plymouth Service Technical Manual Models AV-1, AV-2, AR-1, AR-2, AP-1, AP-2. (81-570-5450)
I've been through the group index, The index (rear of manual") practically page by page. No where is the fly wheel discussed, other than the tightening torque for the fly wheel mounting bolts. 60ft. pounds, and to mark an index on the clutch cover (pressure plate) if it is to reinstall after removal. I'm looking for "service limitations and balancing requirements. The fly wheel I have has no grooves, or gouges on it, just what appears to be dark discoloration from sitting a long time and some minor pitting near one of the bolt holes. If anything, it seems to be glazed. Would it be feasible to "break the glaze" with a 100-180 grit 3" disc"? Or does it need reserviced? Thats where the service limits question comes in. There is a new starter ring going on it and a new Zoom 10" clutch.
