I would, just to be sure all the components are made correctly.
Just as you should do with every aspect of assemblying the engine.
Don't assume anything.

I've installed new cams that are a couple degrees off. And i've noticed that factory timing tabs can be 4 degrees off. Thats why you should mar true TDC on your balancer and go from there.

What other components are you replacing during your rebuild?

.. Most of the time you are safe just installing the cam without degreeing it in a street engine... but, as others mentioned, for the last ounce of performance, checking everything (balancer timing markings, timing tab position, cam centerlines, etc.) works best... and occassionally it prevents a headache later...
