More than likely it's the head. They can pull it easy enough and dye check it.
I think there are even pics on here of the common spot.
What were your VTM-4 issues?

He probably does not have "VTM-4 issues"... that light comes on for a multitude of reasons, as Speedlever indicated above.
FYI, the common head crack area is near the spark plug, bridging to one side. Once they put a new head on it, you should be good to go. Be glad you didn't ride this thing to "real" failure. Several members have had the spark plug blown out & pieces break off inside the cylinder, necessitating an entire engine (in lieu of rebuild).
They are getting away clean if only the head has to be swapped out.
BTW, if they are not familiar with this problem, they might 'jump' to a solution that replaces your entire engine with a used one. If it were me, I'd insist on just the head, since your engine has only 75K miles on it. I'm SURE they won't offer you a "new" engine..... but if they offer a rebuilt one, that would be great of course. Unless they want you to pony up 1/2 the cost, that is. In which case, tell them you'll settle for the head ony, and they can pay the whole thing. Yes, I'm overthinking this.
