Flow is tested by sucking for intake and blowing for exhaust.

As to shot peening. It should be done after polishing, see tech article on Metal Improvement site for why. The peeing puts the metal under compression therby preventing propagation of any cracks. It is especially important to the radius edges of the crank throws and all of the connecting rods. Thats what Porsche does to stock S rods and racing cranks.
