UPS and no packing other than one rolled up piece of bulk butchers paper. The box contents - Modded stock rockers, pedestals, 105# springs (in their own box) retainers, rocker bolts, valve cover gaskets, timing chain, tensioner, thermostat. All pretty much floating around. They are the worst company for packing their stuff that I've encountered. But they are taking care of everything except the tensioner. I've only purchased 4 of these in the past and none have had these cracks, or molded markings so I was worried.
