I would do a sonic test in 4 places 90 degrees apart in each cyl before I decide how far to bore any flathead. My builder doesn't like walls that finish out less then .100. Just a thought. Did that on my 59A. Like said above...080 over is not usually a problem, if it is already freshly bored to that you can probably skip the sonic test. Ross has pistons for that.
