96 outback 2.5 head gaskets/ engine swap

ok, bought a 96 outback for 2200 with 170k and blown head gasket symptoms, am up in the air about what to do. if i could find a 2.2 with low miles and 500 dollars or less i would swap it in but i dont want to wait around for motor to pop up on craigslist or some where else. ive read that these 2.5 are notorios for blowing head gaskets but also that subaru has come out with revised head gaskets that seal alot better.. if i was to do head gaskets i would have the heads resurfaced and preassure tested. wanted to know since i will be pulling the engine either way can you have the block resurfaced with out disassembling it (pistons,crank). Am I wasting my time doing head gaskets? i need to keep this as cheap as possible. if i was to do head gaskets with the revised gaskets how long do they tend to last? any help or opions on this situation would be very aprecciated. thanks.
There is NEVER a need to machine the deck of the engine unless you want to raise compression substantially. f the engine hasnt been backed, once you fix the head gaskets its fixed. Cyl heads warp because of all the passages and stress on the assembly, where the block does not have those issues. You have themodynamic, pressure, and spring forces on a cylinder head.
ALso at 170K its not the HG fault they blew, its more likely age. Anycar can blow a HG at that mileage, and they tend to do it too quite often.
Look at it this way, the original HG lasted 170K youll get at least over 100K if not 200K on the replacements.
Pet peve- high mileage aluminum engines be it honda ford gm toyota blow headgaskets, so if the car has over 150K on it, stop picking on subaru
Ok done venting

I replaced the HGs with the 11044A642's...they are THE STi headgaskets and they hold up to well over 700 Wheel HP. As long as you use the stock headbolt TQ sequence, they will not fail. I did not resurface the heads or block. Total cost of the headgasket replacement was $80 for the HG's and cost of fluids. That was it. So, under $150 for the job. It was WELL worth the time and money spent.
Swapping an EJ22E into the outback will NOT be the correct solution. It'll be even more gutless than it is now.
