I am having some water-jet cutting done this month. Included will be some Opel CIH header flanges, made from .375" thick A-36 steel plate. I will be welding half-washers at the appropriate places so the thickness matches the intake flange. Is anyone interested in buying these so you can build your own header? I won't be having a lot of them made, but based on my initial quantity the selling price would be about $43-45 including the TIG-welded washers. My cost will be $36 not including my labor to weld the washers in place. Not a money-making proposition, but it allows me to have enough made to get the overhead down a bit. This is a brand-new design BTW, not a copy of an old Pacesetter, etc., so it is accurate and clean. Same design as the one on my turbo header.
