This is easy. The head issue was for the 2006 model, not 2007!!!! AllAtlasseries engines built after March 31, 2006 have the hardened cylinder heads change.
That does not mean it is impossible for an 07 to have a head issue, but it would not be the same problem that has now been corrected. There were a few earliy 07s that had a problem as I mentioned earlier, but pretty rare and not to worry about. Mine was built Jan 07, runs like a top. One of the best rucks I have ever had really.

I've NEVER been back to the dealership for anything.

 

Hey Rob!!!

 

The only problems I encountered on my 07' H3 was the lower Steering Shaft rattle and the Traction Control Module failing. Most dealers are aware of the problems and It'll be replaced with newly designed ones.

 

My 07 has only had 1 issue with the driver side headlight. It had condensation in it and they replaced it. That's the only problem that I've had. And it wasn't much of a problem, the gave me another H3 to drive while they replaced the headlight.
