What Spark plugs for Afr 165 heads?

I need a set of plugs for my 86 gt with probe dome top pistons and afr 165 heads. It says to use autolite 3924 on afr web page, but they are 3/4 in. and it calls for like half inch on stock heads. Plus I would rather use ngk or something other than autolite. Can anyone tell me which to use for my afr heads.
