I would like to know what other member think about the following pictures.

The engine does not smoke at all, it feels strong, only reason to open the engine was to install new HG.
It seems the damage is only in the top crown, they are SuperTech forged pistons 9@1. My plan for now is to install the new head gasket and use it until I can recover some money as the engine does not have more than 2,000 miles on it. Part of the problem was when at 1 bar the fuel pressure gauge vacuum line disconnected and the engine went lean to almost 15 afr, later when I started experiencing the engine to get hot.
Correction to post:
Under closer inspection the head gasket was fine, not broken at all. It seems the problem is with incorrect piston to wall, ring gap clearances. Same overheating problems even with 2 head gaskets installed with ARP studs.
