Shipping cylinder heads

On trucking companies, R-L carriers may be an option. They do large item shipping from the west coast to the east coast for Amazon, so they probably have a trailer going from one shipping hub to the next on the way there. It may take a month before they get a full shipment to send it out, but it would probably be the lowest cost way. What works for them is to strap them to a small partial pallet (cut down a full size one) for a hand truck and plastic stretch wrap the top.
