This. So much this.
Good assembly lube, never mixing old lifters with a new cam (or vice versa), ensuring the case hardening is up to the job on the cam's lobes, ensuring that each lifter matches its corresponding cam lobe if re-using those parts, ensuring the oil pump and its relief spring / valve are all A-OK are the critical points with making these engines live forever. Along with hardened valve seats of course.
Significant power gains can be had but it becomes an issue of budget.
