Possible head gasket

[SillySonic]

I have a 2013 Sonic 1.4 LTZ, my daughters car. The car has been overheating and losing some water. The oil is black and there’re is NOT white smoke. So, I changed the water pump. I was about to change the valve cover gasket then I saw the spark plug holes with coolant. I am assuming that the only cause for this is the head gasket? Right? Strangely there have been no misfire codes and no issues with idle.

Any help would be great. Thanks.
