They either said the engines were of a certain spec or the supplier of the fancier bits for the engine said they were made to spec. You might have heard it said that the cost per kilo / pound to put something into orbit well most of the costs are just building the rocket launch systems (they literally launch a rocket from a rocket from a rocket), everything has to be within a particular tolerance or spec, the first two rockets could be perfect but because one washer or nut was able to slip out of shape that 3rd rocket could have a panel deform twisting the rocket out of its flight path and two to three dozen million dollars gets wasted while everyone involved just shrugs their shoulder saying "hey we made our part right".
