It's quite easy to do. In fact you don't have to take the engine completely out, you can just jack it up a bit. But you do need to get the heads milled flat, otherwise it just goes again in no time at all. Or maybe I'm just not very good at doing head gaskets.

I did it twice (without milling) and both times it went again within a month or two. So I gave up and bought an engine from a breaker. Now that one's gone too. I hate my Legacy sometimes.

The most annoying bit is the bolt tightening, because the instructions are stupid. Rather than saying "tighten to x pound feet and then increase to y pound feet" they say something like "do up to x ounce inches and then turn y degrees". But no ordinary torque wrench can read that low. You can almost get them that tight with your fingers and even tiny amounts of dirt in the threads makes a big difference.
