timing chain advice.

The 318 I have was a complete rebuilt with all new parts less than 10,000 miles ago, it,s a 1975 motor so it,s painted blue...I am in the process of a reseal just to clean and re-paint factory red....my question is...should I change out timing chain and gears for a double roller set or not bother. The car is a cruiser not intended to be stomped on. It,s a 68 fury rag not a hot rod.
