Spark plug question

[Classy Comanche]

So I'm taking my truck for some odd and end tune-ups Friday. Doing serpentine belt, plugs and wires. Got all my stuff from rockauto.com and was wondering if these trucks are able to run....I won't say any kind of plugs but can they run what I've purchased? These have pure copper cores. I've been told these trucks love copper parts, like they run better. I was curious as to see if anyone has used these plugs before or what. I'm also having my distributor cap and rotor replaced as well. For that one I bought the one that had the distributor rotor included. Truck feels sluggish on take off and I believe it simply needs a refreshing tune up as such. But thank you guys so much, just curious on the plugs is all

NGKs are great plugs. been using them for 50 years.

 

What about replacing cap and rotor? every 30,000 miles plugs, wires, cap and rotor. Get a cap with brass terminals.

I do have a replacement cap and rotor. I bought them as a bundle as a option on here. I think it's brass? But I definitely do have a replacement set. Truck definitely feels sluggish on take off and going up hill.
