    Just throwing this out there.
    We have a 01 Outback with a SOHC 2.5 that came in for leaking head gaskets. Pulled the heads and sent them to the machine shop. Had them pressure checked and shaved. Reinstalled with new turbo oem gaskets from the dealer. Vehicle still gets hydrocarbons in the coolant. We pulled the heads and inspected. No problems found. We then reinstalled them and still over heats and gets hydrocarbons in the coolant. I am kind of at a loss. Has anyone seen the blocks crack on these engines?

    the heads may be flat but is the deck of the block flat?

    Unsure. But the heads were not even that warped. After talking to Erik I think the block is cracked. So either way it needs a motor.
