Arrow Sperry Valve Works header

Folks interested in going together to have 10 sets of updated Sperry Valve works headers made at cost + tooling should private message me. The originals had (4) 27 inch primaries into a 3 inch collector the tubes were held into the collector by fasteners as shown and are well known to the Alfa community. I have a set (as shown) that I can use to duplicate the tubing runs from and plan to update as follows: 3 steps on the primaries 1.50 to 1.63 to 1.75 inches into a 2.5 inch V-band flange collector that is held in place by behive springs on all tubes. This updates the tubes to a Burns Stainless Steel spec. (please read the attached article). They will be fabricated from TIG welded mild steel and will have to have finishes applied by you as a secondary operation. Please note the weld quality of the tubes in the photos. The location of the collector exit and the v-band allows for other exhaust treatments as it turns to go under the car and as the header is a modular design it can be easily modified to suit very specific applications. Fabrication will take approximately 1 month and has to start in February if it's going to happen, which means all in, in January. The price will be $700.00 a set. You should appreciate this for what it is: a significant value play. Please private message me with questions and when you are ready to commit. Thank you for serious posts and inquires only.

See attached dyno sheet for test results with Mike's engine and these headers.

Happy Motoring.
