Best bang for buck would be champions or ngk. Dont be fooled by the multiple electrode plugs giving you better mileage, more power etc. due to simple physics. Electricity will only follow one path to get to ground, the path of least resistance. If you have more than one electrode then the spark will only cross to one of them until it wears out and then swith to another one. Its possible to get longer life, because you have more than one electorde to wear out, but they will all clog with combustion byproducts anyways.

People who try the fancy plugs in these trucks generally aren't happy and switch back to either autolites or motorcrafts. The simple, cheap stuff works best sometimes.

I had a former GM engine engineer tell me that the Autolite plugs tested out the best and that is what he used.

I use either NGK or Autolite plugs, whichever I can get my hands on. Bosch Platinums suck..
