No, valve manufacturers test/use the valves sufficiently before they are sent out - only thing you need to worry about is warming them up before listening, 5 minutes absolute minimum before playing music (to avoid shortening their life span).

Although some tubes DO need more like 5 minutes that's really just being super-careful. Eyeball it, once the tubes are nearly as orange as they are when you've been running for a while it's fine to play music. It all depends on the tube itself and the speed at which the various components and materials within it reach operating temperatures. Also there is a wee break-in I'd say, although likely contingent on the amplifier design, the testing done by the manufacturer and the types of tubes employed.
