According to your measurements the cam LSA is a little over 110 degrees instead of 112
The cam card is asking you to set the cam 2 degrees advanced which would normally put the intake lobe center at 110 degrees ATDC as shown by the cam card
Since the actual LSA is 110 by your measurements that would put the intake lobe center at 108 degrees ATDC for 2 degrees advanced which is where it was with the first set of readings at zero degrees advanced.
Check the cam lobe timing at cylinder #6 and see if the cam is ground more accurately at that set of lobes.
Depending on what you find there will help you decide the cam timing.
