At least have then checked to make sure they are still flat. Go ahead and do the valve seals, lap the valves, and use the EJ255 multi-layer head gaskets rather than the single-layer one that Subaru still sells as a replacement. I replace the o-ring in the oil pickup tube, and the one behind the oil pump also. I don't usually have the machine shop pressure test the heads unless the engine was overheated (or I have no history of a donor engine). Stay warm!I was planning on deciding whether to rebuild or salvage. I will probably have the heads decked as a precaution.
