Impossible to say beforehand mate, as maybe the block and/or heads need decking.
This will affect the gasket you would need to use.
Just mounting another stock thickness gasket (the thickness of which i do not know, sorry)without at least having a look at the heads and deck (see if they are still plane/true is throwing money away tbh, as HG problems will almost surely return.

They have graphite composite gaskets fitted to the 1997 WRX and are 1.48mm compressed thickness IIRC.
A good upgrade for the composite gaskets are the STi Version 3~4 MLS head gaskets (11044AA463) which are 1.60mm thick and are more durable than the composite gaskets,assuming standard deck height and combustion chamber vols on your engine.
