my guess would be heat , heat is a killer will take tension out of rings warp heads valves turbo's
exhaust manifolds bolts an pistons . depending on how the coolant flows in the engine my guess on the exhaust side there is hot spots , sure the engine will cool going by the temp gauge but there is rarely even cooling in a engine a there is always hot spots , that being said metal will compress more on one side if its hotter then the other , so if u water temp is say 200 an u exhaust is 800 over time i can see how the would compress a lil more . one side the head u have cool air coming in an the other u always have hot going out . heat will make u power but it will also shorten u engine life . just my 2 cents
