High flow exhaust Manifolds?

I can’t remember what the company’s name is, but there is a company in the Northwest, Seattle I think, that is making the 68-71 high performance 340 manifolds now. They are an exact copy of those. I, almost went with them, but was able to find a good stock set. Blast them, weld on ear on one of them, and finish coating them. Look as good as new.
