Motorcraft MC AF 42C spark plugs. Anyone runnin' 'em in their 455?

This Motorcraft pplug was recommended to me by a well known and respected Buick Guru. Anyone running them in their 455's? What places can they be bought at? Isn't that a Ford derived plug too?

Thanks Jim. Have you ever tried these MC plugs?

 

Best of my knowlege Motorcraft plugs are made by Autolite... Seems like we've seen something about this before... Are they a non-resistor plug???
