Spark plugs?
Generally, most GM's like AC plugs, and most Fords like Autolites.
MSD recently nixed the idea of platinum tipped plugs with MSD ignitions. Most folks here use MSD or somebody's CD ignition. And most folks here are not using stock Ford heads. There must be some preference for brand, type, and gap setting.
TFS head calls for an Autolite 3924. This is not a Ford plug, but it is an Autolite, and runs fairly well. Gapped at .050". Splitfire 392D runs fairly well also. But $50 worth of Bosch +4's were pulled in a week, so these motors do have their preferences.
What are you folks using for brand and gap setting with MSD ignition?
