The pilot reported that he was in cruise flight when the engine suddenly ran rough and lost power. The pilot attempted to land on a desert road; however, the road curved more than the aircraft could turn at the speed it was traveling after touchdown and the aircraft left the road and hit a berm. During recovery operations an exhaust valve head fell out of the exhaust stack. Maintenance personnel reported that the fracture faces on the head and corresponding stem were obliterated due to peening. The engine was overhauled about 24 hours prior to the accident.
Probable Cause: The fracture and separation of an exhaust valve head for undetermined reasons.
