i shipped a pair of heads once,,,,once. i cut open a large cardboard box, then set the head on it, cut and folded the card board like i was wrapping a gift, used duct tape to hold it all tight. shipped them as 2 units. they even had valve covers on them, they made it there with no damage. ( cross country too) ups. cost like 45 a head to ship plus a 5 dollar roll of duct tape lol
