2017 Fiat 500L Head gasket replacement

I installed new NGK spark plugs on my 2017 Fiat 500L trekking with 70k miles to fix a misfire engine code. Cylinder 1 plug is covered with oil. So I ordered the head gasket (68120413AA) and spark lug tube seals (68120414AA). I am also going to replace the ignition coils with Bosch 0221504711. Has anyone tackled this job before specifically for the 500L? Links videos and /or online guides will be surely appreciated. Thank you.
