The right sparkplug What sparkplug do you guys recommend for a 2000 z28 m6 with a heads and cam package. I have had champion 401's suggested, are they any good?

Is that Delco # the stock plug? I have the stock plugs in it now and havn't had any issued. I'm just wondering if there is anything better I could use.
