Mine looked exactly the same when I pulled the head for a HG job. I suspected a coolant to cylinder 6 passage way leaking very small. The car never really overheated but would warm up with sprinted driving. I used roll-loc disc and sea foam, I then followed that with carb cleaner to get in the piston skirts with compressed air to blow it out. The compressed air helps a lot. Also after you will want to change your oil to get out any cleaner that seeped past the piston. 10k later and my car is great.
