Personally, I dislike trusting witness marks if I didn't make them (or
otherwise verify that they are accurate). Everyone makes a mistake sometimes,
and the factory was no exception.
So, I would first establish an accurate TDC using a piston stop or similar.
Maybe your eyes are better than mine, but I can't reliably see a 1 degree error
in the slot being "downwards".
