umm. they stopped production over 2 years ago. i know the owner of the foundry Bob reasonbly well & was offered some of the equipment that wasn't being shipped to China. I was loading up my trailer when the furnace was being dismantled. that foundry is now a storage facility storing Chrysler Crossfires & Jeeps. i drive past it every other week, not much changes there. there is no way they're producing these heads here now, if they were i'm sure Bob would have given me a set as he was one of my sponsors a few years back.
