Looking at the chart is somewhat confusing, It looks as though the section that is the K or F is a special?

I would pull out one of the plugs and compare it to one of the new ones paying particular attention to the plug seat shape as it may be different.

Also look at the electrodes, sounds like a different design. Not sure if it matters if it has one electrode or two or if it will affect the long term durability of your ignition system.
