Default AC Delco R43 Spark Plugs

I found a set of never used AC Delco R43 Spark plugs with a date of 1995 on the box, are these considered "nos" and weren't they used primarily for 302 small blocks in '69? Do they work better than the Autolite plugs I'm currently using or are they just correct for that motor?







Thanks!
