Which spark plugs work best with gt40 p Iron Heads?

Autolite 764's

Same as 1993-1995 Mustang Cobra 5.0

If you need other brands Like motor craft I think there 32c? or 42c? I forget which ones, But its one of them,

Dont waste money on iridium, Or platinum, Just get Coppers,

I use motorcraft but my next spark plug change im gonna try autolites
