"NOS PLUG HELP"

Have the ole school 1969 model heads on my 514 , 13\16 plugs.Ordered NGK -10 ,they sent me what they said was a -8.Look like a autolight 45 to me. Dude said that was the coldest he could get for the 13/16 style plug,planning on spraying 200-250 shot with bigshot plate.Autolight # ?, Champion # ? THANKS, MAVMAN
