School me on re-using a new(ish) camshaft

I think it will boil down to the individual.....and it reminds me of a Dirty Harry quote:

Personally, I would get new lifters and take EVERY precaution to break it in properly. Break-in lube & oil and even softer valve springs.

You can get rid of the power brake booster, but it may require changing the master cylinder and proportioning block too.
