A basic stand is fine for finding leaks,braking in cams,setting basline timing and jetting settings. I know that many think modern rings with quality bore finish seat instantly,but I still like to put a load on them from the start and the reason I don't have a run in stand. If your confident you won't have leaks,the cam won't go flat and timing and jetting aren't a problem then it's use becomes less needed. If your building engines to sell to customers then it makes some sense to confirm all is clean when you deliver the engine.
