I'd swap them out for multi-layer steel gaskets and new head bolts. Given the engine is in good order and hasn't had a gasket failure yet I'd say you'd be fine skipping the head decking and just install the new gaskets after a good cleaning.

Pros: good order, easy cleaning

Vehicle: Subaru

The fel pro gasket set and head bolts + head bolt tool will be close to 300 and then you'll need RTV sealant. Another probably 200 for the Aisin water pump.
