My engine went just fine for 14 years until I ran it too hot and lost an exhaust-valve seat. I was running it at cruise rpm on the ground, concentrating on a propellor-balance device.So kgwilson and Dave are right. Cooling is the critical thing. You need to do better than the factory seems to say, and then the engine will go for years and years.

I can think of several. How about the two gentlemen from WA who picked up a new one at Bundy, and didn't make it pass the ranges before coming to grief ???...............Maj...
