im assuming your trying to decide between twin leg an single leg stands ?
single leg will do it fine, however they can be quite unstable, you need to be carefull manovering it about loaded up, it can and will tip very easy an it will proper damage the engine.
if you dont have a good flat level floor i strongly advise the twin leg.
also when you tip engine over if the head is still on it will be top heavy, using only the bar to turn/control it will go over, you need to stand side on an control the engine its self
