5985590 is the cylinder head casting number (part number), which has nothing to do with the date.



The casting date stamp is what shows October 1983 on this head. It's a little symbol that looks like a sun, with the year of manufacture in the center (83 for 1983) & a certain number of dots around the perimeter (each dot represents 1 month, so 10 dots = 10 months = October). The date stamp looks like this:



You'll often see this on large cast alloy parts like cylinder heads, intake manifolds & on the back of Cromodora alloy wheels.
