Most believe over-rev damage is incremental. Likely valve springs are most impacted - lose pressure once exceed their design limits.

Obviously, if it didn't scatter - no issue, but don't think anyone can guarantee long term health...then again, a production engine is pretty robust - few LT1's seem to be have been lost.
