Don't spend big bucks on fancy plugs - NGK TR55's (stock number 3951) are fine.

Default Plugs
With an 11:1 408in engine should a hotter or colder plug be run?

NGK TR55s gapped at .050-.055. TR6s gapped at .034-.038 if you plan to spray, those are what I run

Definately not hotter. I would say TR6s would be good.
