The manifolds on my Holt were purchased from the seller when I bought the original drawing set. When I made my drawings I drew up the manifolds to be a fabrication from either steel or brass. The design of the originals are very curvy and almost impossible to duplicate without using CNC, drilling and plugging. When I built my 300 six engine I made the manifolds as a fabrication from steel and silver soldered the parts together. They turned out very nicely. There is a build thread on it. The bottom line is that my manifolds aren't the same curvy shape as the originals. A drawing would have to be made to copy the originals and I don't want to go there. If someone else wants to be my guest.
