Had a ‘76 440 years ago that had cam bearings like that, all were touched, some worse than others. I HAD to get it together ASAP and didn’t have time to buy cam bearings, install tool etc. My super greasy solution was to get a two part epoxy that was made for oil (can’t remember which one) filled in the chips, let it dry, knocked down the high spots with a 1/2 moon file, and slammed the old cam in and spun it a bunch of times til it felt decent. Jammed in a new cam and away I went lol. Hate on me all you want but it ran fine and had good oil pressure. I figured the epoxy was probably around the same softness/hardness as the Babbitt they use in bearings so why not!
Obviously if you have time replace the bearings, but if your stuck in the middle of the desert and happen to need a cam bearing fix and have some epoxy give it a whirl
