bike is 04 electraglide classic mostly used for touring  ride in 3000 rpm most times

It's a broad term what is hard on valvetrain. How do we quantify that?

I guess I should have been more detailed ........while I think these cams are great and have lots of power in my riding rpm I use the bike for touring long distance and just wondering what the life of my valvetrain is going to be or how often I should be checking /replacing my lifters '
thanks

If you did adjustable push rods don't worry about them and replace them at 50,000
