It's been a long 6 weeks. My rig blew both head gaskets in Moab after the radiator fan went into the radiator, and since I couldn't remove the head studs w/an 1800lb/ft impact (turns out this is a common issue), I opted to drop in my spare engine. Did 90% of the work myself (a friend graciously came over after everything was disconnected and we maneuvered the old engine out and dropped the replacement in) in my garage. Started 2 weeks ago today, and she fired up last night. I'll update this thread with a recap in the next week or so.
