Which plugs are best for the LT1

What plugs do you guys recommend for the lt1? Keep in mind my engine will be mostly stock. Just with ram air, headers, tune, and ported heads.

Those recommending the Autolite, why don't you list a part number?

I never ran the aluminum heads on a stock motor but I am guessing 106 or in some cases maybe 104. I know the 106 is a touch hot for the iron head motors but I think it may be good for a stock aluminum head motor.
