Anyone need a side job in Los Angeles CA?

I am not on board with some of the other comments here.

If the bearings are there and not trash, leave them for now.

If it lost a lobe, depending on how much wiped off or how long it was ran there is a lil junk in the motor, but so?

Heres the reality...
80's chevys lost lobes all the time and we would just pour oil through it to rinse the pan and stick a new cam/lifters in and away it went w/no issues that caused failure/breakage afterwards.

I have seen motors run after being built where they were not cleaned after machining, and while the bearing were valley'd/grooved from the debris...it still held good psi and ran fine.
Back to reality, if it lost a lobe with the previous owner...chances are it was all run through the bearings already and run for a while till it really acted up, so whats a new cam/lifters and run it gonna hurt?
Stick a magnet on the bottom of the oil pan and oil filter to capture/contain the bits.

So unless you want to have to rebuild it 'just because' , stab a cam/lifters in it and go.

I'd do it.
