Before getting too far into this, though, you may want to do more diagnostics on the motor to be sure it is a headgasket.
This is very true. Taylor, you might want to check the current injection pump timing too. If the timing is retarded, or just very off, it can cause higher than normal engine temperature.

v8volvo: Is the change in head bolt the only modification needed to use an early head on a later block?
