John - The exhaust manifold with casting# "839130" is an early one for ALL 1940-46 Chevrolets except COE models per my 1929-46 Chevrolet Master Parts Price List. The correct casting number for a matching intake manifold is "3835150". Again, fits ALL 1940-46 Chevrolets except COE models.
Your pictured angled back exhaust manifold definitely looks correct for your 1960 235. Do you not have an intake that came from the 235?
