The most overlooked item when tuning your engine  , performance engines with big cams, bigger carbs, better exhaust will flow more air and burn more fuel .
This will make  the internal temperatures of the engine  hotter .
This will then require a plug that can dissipate the heat better  to maintain correct plug  tip temperature  to prevent pre-ignition . 
Plugs should be regularly checked for condition . 

AC7C  are designed with a shorter tip and allow the heat to move away quicker 
Keeping the plug cooler
