I did the same job at home too on my 2015 yukon xl denali 6.2 engine. except i replaced all the lifters and the cam. the only thing i added to your list was the VLOM, as it is recommended by GM to replace it during any AFM failure. Plus i suggest a careful inspection of the cam lobe. i believe my bad cylinder was also #7. Also i had to buy some more tools to properly install the head bolts. ie torque angle gauge and 1/2" large hex bit. Its been running fine with 100K miles after the repair and no leaks or issues. Good Luck! Definately cheaper than going to a dealer.

How many miles on the vehicle?

You will need new head bolts. The factory ones are torque to yield and can not be reused. You might as well replace all lifters on that side while you're in there too and if it were me, I'd do both sides. The lifter cup should be OK, no reason for the m to fail. Make sure you have a good understanding on how to torque the rockers.

How many miles on the vehicle?

If the question is for me, 206K miles at time of repair. Currently i have 302,000 miles on my 2015 yukon xl denali. Mostly highway driving obviously.
