    Well, honestly I’ve never flattened a cam lobe before. The initial plan was to pull the cam and swap in a new one, new lifters and perhaps pushrods, oil change and call it good.

    I really recommend you examine (and replace if needed) your rod and main bearings... there could be a lot of metallic crap that bypassed the filter. Also take the oil pump apart, it may be damaged/worn too.
    Is it just one lobe so far?

    Just one lobe. Had a lifter collapse, and I thought that was it. Upon pulling the intake I saw the cam lobe plain as day, right there staring at me. The engine is a fresh build, maybe 600 miles on it. 20 miles driven after first hearing the bad lifter.
