welcome to the forum. You are correct, stick with the coppers or NGK 5306. What year truck? Depending on how beat the engine is, why not just do a head job which covers most all of the common problems? Valve springs, exhaust manifold bolts, and various gaskets. These engines are very tough if even given minimum maintenance. As for cams, since it's not your truck I'd recommend a basic RV cam without the need for custom tuning.
