Regarless of the miles on them Crane says you must replace them with a new cam. It evens says if you only have a dyno run on them to replace them. Now I sure wouldn't do that but I would replace them with anything over 70-80k on them. The stocks will run to fit that cam. You can get them for them for $100 from Mustang Unlimited and they're Crane. Save your self the hassel of breaking stuff, and even tearing up your new cam.
