Or, if you have problems with this, just change the heat range.
Personally, being an aircraft mechanic who hates putting thread inserts
in air cooled engine cylinders, I have used anti-seize since 1973 and
never have had a dead spark plug and never had indication of needing to
change heat ranges from its use. Used sparingly, it does its job and
transfers heat just fine.

Everyone is missing the real reason for not using anti seize.  The plug
transfers heat thru the threads to the cylinder head.  that's why you have
different heat ranges on spark plugs.  The heat range is the ability to
transfer heat from the red hot plug to the head which is cooled.  You
shouldn't use anti seize as it gums up the metal to metal contact.
