Yes, the N-frames have the 'endurance package'
Generally speaking, the best external indicator of its presence is the longer notches machined in the cylinder. By 2001, the package was 'standard equipment' in all models built on the N-frame, including the Heritage Series.

Of course, exceptions exist. I saw a Model 24-3 with a 'long-notch' cylinder and a probable factory refinish at a gun show several years ago, so you never know what you'll find out there.
