Default Spark Plug change interval?

I have a '86 coupe with cast iron heads and stock motor. how often do I need to change spark plugs? it's been about 12,000 so far.

I have replaced the injectors with ones from FIC and changed the distributor cap, rotor and wires when I did the plugs 12,000 ago.

I have not yet changes the one O2 sensor on the driver's side and I just turned 87,000.

not as smooth as it was under wide open throttle.
new fuel pump, filter and 40psi at the regulator

Stock motor with stock plugs has a change interval of 30k.

They say you can go twice as long if you put in platinums but at this rate it will be 1,322 years before I get 60K on mine.
