Well in this case it sounds like a reputable and knowledgeable shop diagnosed it, and likely are correct. Have the heads machined by a machine shop before you reinstall them to give the best possible chance for a good seal. And be sure to be familiar with the torque sequence before tightening the head bolts. You do not need new head bolts on Subaru engines. Tools. You will need a 14mm 12 point socket for head bolts. At least 1/2" drive. An accurate torque wrench is a must. A torque angle gauge may come in handy, but if you are good with judging angles (90°) it's not necessary. Other than that, an assortment of regular hand tools, metric sockets and wrenches.

Pull the tail shaft and transfer housings off and check out the transfer gears and center differential assembly. Those can all be replaced without a complete tear down of the transmission. Anything forward of that requires the case to be split, and generally means you should just get a new used transmission.

Are you SURE it is leaking from the head gaskets? 2.2 head gasket failure is rare. Oil leaks are not, and quite often oil leaks can appear to come from the head gaskets, oil pan or rear main seal, though they stem from other sources. There are three places that very commonly leak on this engine. The valve cover gaskets, the cam seals, and the oil separator plate. One seal in particular that creates a lot of problems is the rear cam O ring on the back of the passenger side head. It's under a metal cap with 2 bolts securing it to the head. Remove the bolts and twist the cap to remove it and the O ring can be swapped. A generous coating of oil and a little twist the cap will slide back into the recess in the head. There is a similar seal on the driers side head. It's a round plug seal. It's very difficult to change with the engine in the car. Mostly because it has to be pressed/tapped into the bore.

Using Zip ties can help hold the belt on the sprockets while you are trying to get everything set. Once the sprockets are set to the proper marks, I hang the belt, zip tie it to the passenger cam. Then rotate the cam by hand a little to give some slack while I set the belt on the crank. Turn it back to take the slack out, adjust if the mark doesn't line up. Then I set a wrench across the top of the crank sprocket, between the belt and the crank sensor. This holds the belt in place so I have two free hands to set the belt on the drivers side cam. A 17mm wrench, or socket on a breaker bar to turn the drivers side cam just a little bit clockwise away from the timing mark, pull the slack out of the belt and set it on the sprocket, turn it back to the mark or until the belt has no more slack. Adjust if necessary. Hold the belt taught by hand and move the tensioner bearing into place. Once the bearing is there the weight of it will keep the belt in place, move the wrenches out of the way and bolt on the bearing.

I saw the good side first, and thought I might have found a good white hood for my wagon. Then as I got closer and saw the OTHER side... It was good. Actually it was nearly perfect. Certainly worth paying $50 for. One small ding, and a couple small chips in the paint near the grille. Until that happened of course.
