Auto zone, AAp will loan you a tool, basically you buy it and when you give it back they refund money or cc. I personally would use the new copper nickel alloy stuff but it will change to a coppery type color so it will not fit a factory stock anal retentive style repair. It bends very easy does not try to kink and is easy to flare, the only drawback is kind of pricey.
Cam bearings I would not change unless you see something obvious or low oil pressure. They are a pain in the ***, special tool to install then they need fitted/checked with a cam, scraped, filed, etc.
