I have three coming from Germany and from what I am told production is going to be stopped on them. It has taken a year and a half just to find these. They will enable you to reuse the head in the event it needs to come off unlike oring'in the block or head, then it has become junk. I don't know about you but I got two months and about $5k in my head so I would like to use it again and again. E-mail me if you are interested. They cost about $400 and are worth every penny as we run 32 psi and have never experienced a head gasket failure.
