what autolite plugs for gt40 aluminum heads?

Hey all,

What Autolite plugs should I be using with my GT40 y303 heads? I had some Bosch platinums in there before but they are crap and I am looking to swap them out. Any advice would be appreciated.

Motorcraft AWSF-42C...some 93 GT-40 Cobra motors had AWSF-32C plugs. Not sure what Autolite's P/N is.
