A new pair is like 56 bucks, are they reusable when I replace my rocker arms?

 

I would think that if the rockers were worn enough to need replacing then the shafts are too. but its harder to tell. So.. I wouldnt re-use them

If you know the measurment you could take em to a shop and have them look at em.

 

They arent worn out, I just bought a new cam.
