I took a different approach. I had a local exhaust shop bend up some of the correct dia. exhaust pipe to make the long runs. Short straight pieces of hose hold everything toether. Painted the pipe the same as the block. Looks good, low cost and no strain on the alum. radiator. (Tip: Put a ridge of some sort at each end of the pipe so the clamps won't slide off when the preasure builds)
