I'm currently running Autolite 65 plugs in my 392's, one motor is slightly modified and a fresh rebuild and the other is original stock apart from having heads rebuilt , but I think both may be a little on the cold side and was looking to go up in heat range. Can any others running early hemis let me know their experiences/advice and what plugs they're using.

Thanks
Owen
