I would imagine that the necessity of a tear down would depend on how much power you are making and how hard you are spinning the engine. Other factors would include the quality of the build and how good the tune is. One other factor may be if you have OCD ...lol . That being said, I make right at 1,200 HP and spin the engine as high as 8,400 rpm at times and have just finished my 3rd season on the engine. Maintenance is to perform an oil change and adjust the valves at the beginning of each year and that is it, outside of spark plugs that get changed somewhat frequently.
