Firing order of 5.7 HEMI?

Hi guys!! I'm wondering what is the firing order for the HEMI 5.7, while on full use of all cylinders and with MDS. Also, which is the cylinder position for the same engine... because I changed the spark plugs and want to know which cylinders had clean combustion vs some oil residues. Help is appreciated.

The cylinders are numbered from front to rear; 1, 3, 5, 7 on the left bank and 2, 4, 6, 8 on the right bank. The firing order is 1-8-4-3-6-5-7-2.

Cylinders 1,4,6, and 7 get deactivated when in MDS mode. I'm not aware of any change in firing order while in MDS mode.

This info definitely answer my questions!!! Thanks Mnunes, your information is very valuable to identify the removed spark plugs condition, due to a code shown about the 8th cylinder misfire. Definitely, the spark plugs change has made a BIG difference!! Now the idle is very smooth, and the car is more responsive when needed. I didn't know how important the plugs could be for the HEMI performance...
