Best spark plug

[turner]

Just wondering what everyone is using for spark plugs. My engine is 9.5 comp stock cast iron intake with rochester 2 barrel. 350 ci.Hei ignition. I run pump gas as well.I always run Ac r44 ts plugs. Any idea if there is a better plug out there? I have never had any trouble. Thanks alot.
