So at 110K my 2010 head gaskets failed. So I payed $2500 for head gaskets replacement that included the heads and valve seats resurfaced, new water pump, thermostat, fan water temp switch, and oil pressure switch. I also had them use the 5th Generation Subaru recommended blue antifreeze. We used Peak OET blue from Autozone.
Anyway now my car has much more power and pep when I hit the pedal. Not sure if I am going to have to do this every 100K miles.
