valve springs

I am not sure of max duration limits, but why not replace the springs with it. They are cheap and after any amount of miles it doesn't hurt to replace them, especially if you are doing the cam. I know this isn't the answer you are lookin for, I can't remember which one but one of the recent engine building mags had an article on this. Sorry I didn't give a better answer.
