But lets see what other things people suggest - there will be other reasons i suspect...
Head you don't know history of could be from bike run dry of oil and cam bearings shot, valve oil seals and guides could give problems. Could've been run dry of coolant and overheated and possibly warped.
Or it could be in perfect condition.
