it is the cross reference for an autolite ar 3911 exept with a full tip for longer life
you will definitely mess up the plug threads if you jam an acorn seat plug in an all pro head.

Thanks been a while since I tinkered with the Formy. I'm spacing out (maybe lack of sleep due to new baby), but what was the concensus around the AllPro heads, we need a gasketed plug since the plugs are more recessed?

yes this is the plug that stays in the car full time. i have not worn out a set yet, but i have replaced them when doing head gaskets etc. just for good measure.
they will last as long as any other normal car spark plug would. they are not a racing fancy tip short life type of plug.
