Looks like the wrong carburetor to me. I believe the fuel inlet should point forward from the upper center of the bowl. That gets the fuel line and filter bowl, if present, farther away from the manifold.
(They're still too close, in my opinion) Also, the often missing fuel pump heat shield can help reduce hot fuel issues. Late initial timing or malfunctioning spark advance will cause the exhaust manifold to run hotter, which can contribute to hot fuel issues like vapor lock and flooding. Modern fuel blends are not well-suited to carbureted engines. The modern, EPA-approved gasoline blends are designed to be held under pressure, which prevents boiling of the fuel in the hot underhood environment. The more volatile properties of EPA gasoline aggravate flooding and vapor look issues with older cars that have atmospheric fuel systems.
