Clifford Headers for a 225?

Anyone with experience with these? I thought Dutra Duals were about the only option besides the stock manifold.

I debated on commenting here, about this, but I looked at these some 30 years ago. Back then I placed an order and I got a notice that when they get enough orders they'll make them. I canceled the order. I have to make a decision too. I'm leaning towards having a pair of Dutra duals made. Don't know who or how, but I wouldn't put a Clifford product on my car.
