The heads are off! Working alone it took me 3.5 hours to get them both off the engine and onto the work bench. Would have taken a bit longer but I already had the timing belt components removed. I could not make up my mind on whether or not to remove the engine. I left it in and everything went pretty smooth. My biggest worry with leaving the engine in place is possibly damaging the new seal when I try to put the head back on :-\
Some notes:
Didn't have to open any AC lines--yay! I zip tied the AC pump out of the way where the battery would normally be.
The head bolts SUCKED to unthread because they're three miles long. A small 90º air wrench would have been great here. I backed them out with a ratchet. Then once they were out enough I finished removing them with a ratcheting end wrench.
It's nice having everything on top of the engine. I climbed under once and that was to remove the exhaust (which conveniently drops out of the way).
Spark plugs were burned down to the porcelain
I'm sure they are the original plugs should I be concerned? Pistons had some little white spots on them along with the normal carbon buildup. Cylinders look brand new.
Not sure if I should have the heads re-surfaced. I think the gaskets were leaking because Subaru uses crappy gaskets.. it was leaking oil not coolant anyway. Thoughts? Recommendations?
Going to order Six Star gaskets and new bolts from AWDA. They seem to have the best reviews and a greatly improved gasket design:

Just curious: I've heard the 2.5 has two iterations: timing belt and timing chain. Is this right? And which years have which?
Not sure on that one. There's two versions of the 2.5 like mine (phase 1 and 2). I know they used this motor up to 09 (maybe longer) and it uses a belt.
