You must get a better sealing/surface finish than I do.
Let me know when you are doing this again, I will try to visit for the day.

I follow your procedure almost to the letter. However, I found that the blade can pass over some of the gasket material that has been effectively fused to the surface of the block. Although you believe it's perfectly flat, the use of a stone will tell otherwise.
The stone is not for getting a flatter steel surface...........it's simply for feeling the drag of some gasket material that is not completely disengaged from the block face.
There is danger in using the stone..........very fine particles can enter the oil passage. It's mandatory to wipe this opening carefully to eliminate as much residue as possible.
I don't believe the entire process is completely without any oil contamination. Hopefully, it's not severe and will pass to the filter.
Believe me............I don't intend to ever do this project again.............one 617.........one gasket change in my lifetime.
