How much resistance on a CB650C 1980 in spark plugs?

I have a cb650 that seems to only have 5k spark plug caps thats it. Looking at other posts like Hondaman at SOHC it says 80's bikes came stock with 10k ohms of resistance which extends the spark. Should I change the spark plug caps to 10k ones or add the dr8es resistor plug which is 5k to increase it to 10k ohms?
