Camshaft bearing replacement a must?

[slimguns]

Hey guys, decided to go with a cam instead of rockers on my top swap. I've read I "need" to replace my camshaft bearings but I rarely hear anyone say they do it. Is it a must, a recommended item, a good thing, or a if you can why not?

TIA,
Slim

if your pulling the engine out i'd change them. its not that hard to do.

once your cam is out if not pulling the engine you can look at them, if you see copper metal showing, they are worn out and should be changed. still shinny metal, they should be ok to re use.
