I have a head I bought for parts that has an excellent exhaust camshaft that I would like to use for another engine. Some knot head broke two teeth off! I don't know how. The amount of chain that wraps around the sprocket leads me to believe that it could potentially run forever with two teeth missing with no issue assuming I knock down the sharp edges. Also wondering if anyone has replaced the press-fit sprocket on these before? Is there anyone out there that could do this for me?

I wouldn't run it that way for one minute. MegaCycle might be able to do that for you, they've worked on 450 cams for over 40 years

Cheapest way is to get another cam, you can swap the sprocket onto yours if your lobes/bearing journals are in better shape.

I know when timing chain broke on the freeway, I could hear the chain throw itself agains the bottom of the engine as I went on to bend valves. I had crimped the master link too tight losing flexibility of the link.

The last engine I took apart, the master link wasn't where I wanted it to be so I took a link that was available and used the Common Motor Collectives tool to push two pins out and on reassembly, reused the same link and no new link. I think the friction of the old link will be enough to keep it in place, just as extending a drive chain. This is off topic other than related to the cam sprocket.
