Believe it or not they aren't that heavy (as compared to the other common style). The problem is that the pattern has to be dead nuts accurate or they won't fit, I need an original set to create accurate digital files, heck I wouldn't even need the manifolds to be in my possesion, I'd only need thier owner to deliver them to the digitizing company for the work which would only take a few days. Either way, I'm willing to do whatever it takes, these things need to get made!

A cast iron replica would be made.....Along with a (much) lighter steel tube version that will look identical in shape and contour, this will allow for modifications to the shape by heating and bending to allow them to fit into other cars not originally designed to accept them.
