i got a set of Acdelco plugs today and their gaped to .26 should i leave them or put them at .28

Im planning on replacing my spark plugs in my 2012 Cruze Eco with 75k miles and I need to know why ACDelco lists 2 spark plugs for my vehicle and what the difference is. Also the Cruze manual says my spark plug should be the 41-117. What did GM offically announce about the gap ? these list .28 I will upload a picture thursday of what my spark plugs look like after 75k miles and averaging 50mpg actual for anyone who is curious. Thanks for the info.
