Subaru should not make their head gaskets out of kryptonite.
For the record:

The head bolts will often make terrible noises, and won't turn smoothly, making creaking or cracking noises. You must follow the correct sequence to undo the head bolts. A big breaker bar is your friend here.

So, when I went to pull the cylinder head, it sounded like I did everything horribly wrong, so I got terribly distracted trying to figure out everything. Allegedly, I just needed to keep wrenching. I could have finished the head gasket replacement by now!

I had to remove the bolt holding the crank pulley on when I installed a lightweight under-driven pulley on the Acura. The 2 foot breaker bar wasn't even close to breaking that sucker loose. I ended up adding something like 5 ft of pipe to the end of the breaker bar, and standing on it (185 lbs) wasn't enough. Finally, I bounced on the end of the bar and the bolt let loose like an explosion. I feared the worst thinking the bolt had sheered, but to my amazement everything was fine. Of course, I did break 2 sockets before I found one strong enough for that kind of punishment.
Good luck!

We once used the weight of the car and a lift to break loose a rear axle nut on a 280ZX, with a 3 foot breaker bar and a big crow bar.

I took the rear bumper off the Albatross to install a hitch with a ratchet and a scissor jack. I didn't have many tools back then, but the dead weight of an SUV can be used to apply a lot of force.

At work, we once had to torque an eyebolt to 3000 ft-lbs. An adaptor welded to a 15 foot piece of pipe, a deer scale, and three men on a rope got us there.

Great stories, everybody!  I just needed to pretend that all of my ex-girlfriends were complaining at once, and I made it through the horrific sounds the head bolts made as I pulled them.
I pulled the cylinder head! Wow that thing was dirty! Awkward, too! Dirty and awkward! Also, the SLP called me, so I have a schedule to do my hours! (I am trying to become a Speech-Language Pathology Assistant).
