Depends on what kind of block/heads. Also what are your plans for the motor?

Stock HG work well went prepped and torqued correctly. I wouldn't recommend custom HG's to change CR if that's what you are planning, there are better ways

I vote OEM. I know that at least on the 2.5 NA DOHC and SOHC the gaskets are MLS which are verygood.

The stock head gaskets are MLS and really good. I do a lot of work on 2.5 NA engine and always use factory subaru gaskets. For turbos the factory gaskets are good for the typical street car, with typical "stage 2" etc stuff.
