Spark Plug Help

https://www.napaonline.com/en/p/NGO2635currently running Autolite plugs in my ol 65’ Dart 3.7 225. Ran for a day and then took a ****. New carb, new distributior, wires, cap, rotor and plugs. Mechanic thinks it’s crappy plugs. I purchased NGK V-Power and the old dude behind the counter was pretty hesitant and said “it usually requires Autolites” but I said no. Am I okay putting these on? Or will it mess something up? Thank you in advance!
