Forget the swap, you will be biting off way more than you can probably chew. The 22rte and the 3.0 are very similar in power. The work/benefit ratio is completely not worth it. If you can't replace the head gasket, just put the motor back together and check your phone book for a place that will replace the motor. There are places here in AZ that will do it for less than 1500 with a 5 yr warranty.
