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

A friend put a camshaft in a 273 for a customer. After an unknown run time (I was told break-in and approximately 20 miles), it was decided the camshaft would not allow the power brakes to function properly. The customer decided to have my friend replace that camshaft with one that would allow the power brakes to work correctly.

Now my friend has this camshaft and wants to know if he can use it in a car without power brakes.

I'm camshaft dumb, but I think I've heard that to re-use that camshaft, he would also have to re-use the lifters (in the same lobe location) that the camshaft was broken in with.

Thoughts?
