[DeTomaso] Sparkplugs

I'm running Autolite 3926, but it's a small plug - for the A3 heads.

I bet the AFD heads also take a small plug.  I haven't seen a new alum head
yet that takes the old style big plugs.

I was fouling Autolite 3923's.

That's a totally different plug.  I guess I should have stipulated that 
I run stock cast iron 4V heads.  What are you running Will?
