Ok guys I am changing my plugs on my gn1 heads. Old plugs were autolite 104 and thats what im replacing them with. Where should I gap them at ? I am running 25 - 28 #s of boost and pump gas 93 octane with alky. Old gaps were between 32 to 35 thousands , but I was only running 18 #s and no alky. Thanks on the help.
