Should I buy 2001 Subaru Outback with rebuilt engine? It overheated

OK guys, thanks so much for all the comments. really helpful. So I went back to the mechanic and asked for a list of all that he did when he “rebuilt” the engine. He gave me this list -

  • complete valve job
  • resurface heads
  • Head Gaskets set - complete
  • Head bolts
  • Waterpump
  • Timing Belt kit w/pullies
  • radiator

  • new tires
  • brakes
  • used P.S. pump
  • used AC compressor
  • all fluids changed

I think he did a pretty complete job. And I looked up some reviews of his shop online and he seems pretty reputable. I drove the car yesterday for about 20 minutes, got it up to speed and it drove so nice. Checked the oil myself to see if there was water getting into the oil - all good. Also looked around the engine for any leaks - nothing. What do you think?? Did he do what he said?? Is this car a good deal??
