I would use Autolites and gap them .035-.040

Hey, i use champs or (gag)A C Delco. In my everyday ride, I change them twice a year for top performance. In the hot rod its only once because of limited use. I have had a bad
exper. with autolites in my MoPar. Slugish performance. JVMopar may have not. They do last longer . The tip seams to lastlonger.
An MSD or better will improve plug life.
Stock gap is .035 on most, .040 is fine.
