To add to Carey's point.
AMG further complicated matters by having used crappy head gaskets as well, gotten from the same crappy manufacturer that GM used. Both a bad head gasket AND the cracked cylinder issue show similar symptoms.
The ONLY way you'll tell properly is to pull the head.
With that being said - a replacement engine is 3k if you shop around properly. Engine swap will set you back about 2k max.
I would worry more about:
-Upgraded A/C (97.5 or higher)
-Been well maintained
-Low mileage
