I would replace them. They're already off and 20+ years old. If the car sees lots of city driving/idling then I certainly would. The price is minimal all things considered.

Also, since you'll have the valve cover off, check the breather hoses from the cover to the intake. These are almost always brittle.

I'd think about some valve stem seals too due to age. They're less than $10 and should take 3-4 hours to do.
