I doubt most yards would let you do any tests on the motor, but you could ask. If I had access to an engine in a car, I'd be happy with a good compression test, and one of those coolant tests that can determine if combustion gasses are in the coolant.
I wouldn't swap heads if you get a motor with 60k miles. You could drive it for several years before having to do the valve seals, and you may have parted ways with the car before that point.

I was suggesting swapping heads as from what I understand he just had a valve job and decarbonizing done on his heads.
All junkyards warranty the engine as replacement only and for a short period of time. Not selling you a bad engine is part reputation, and part the reality that there's a lot of labor involved for them to remove an engine. There is no shortage of X5's in junkyards so they will sell you one from a car that came in totalled in a wreck where it's fair to assume it was running, the mileage is known, and had passed smog at most 2 years ago. Cars that are sold to them with expired registration or from the impound lot they just assume something is wrong with the engine and might pull the heads off to sell but with engines as popular as ours most likely straight to the crusher.
