nothing wrong with ngk but with a 100 hp i would run 7 or 8 or the autolite ar3934 that what i use for a 100hp which is ngk 8 i spray a tune of 42n 36 f 5# fp total timing 30* its around 70hp and run the ar3923 with this tune the truck is only a tenth off 150hp hit and the ar3923 work great on the street

ngk's are pref. because the tips will burn away in a lean condition. The strap on a autolite is thicker and does not go away as easy. Kind of a safty thing.
