Click on "Links" at the top of this page. Click on "Parts" on the left side of that page. Scroll down the new page to the section called "Performance" and select the vendor you want. Clifford is listed there as well as the Stovebolt Engine Co. Some of the others may also have the split manifolds, but I don't know.
It's good to hear from someone who has less posts than his Stovebolt number.
