Use the MLS headgaskets... subaru part number 11044AA770. I never use the single layer gaskets when I do NA motors. Also stick with OEM parts. Especially when doing head gaskets.

Mine went at 180k and took the engine with it due to loss of oil pressure.
My 2006 head gaskets were leaking prior to 130k. Ticking time bomb in my opinion.
replace them with the head gasket from the EJ255 or 257. They’re made of MLS and most shops do that in order to make it last longer since they rarely blow.
Mine went at 160K so it’s coming soon. The single layered graphite that is on there now will always wear out quicker with time. It’s a “design flaw” and will always go out quickly.
642 head gaskets from a similar year wrx. Don’t use the same 633 or you will have the same problem again.
the EJ25D, famous for blowing its head gasket and mixing oil and coolant inside the motor (in-laws had that happen, twice).
The Tig won't need head gaskets at ~150k like every other subi does. The TSI pretty much has reliability nailed down now, IMHO. Change the oil and drive.
