They do look suspicious. Agree that you should not use them.
One thing I'd do, given the engine is apart, is to check your new lifters in each bore, less the cam. Slide in each lifter with a light coat of engine oil. Rotate each by hand and see if any hang up in the lifter bores.
Often a wiped cam comes about when the lifter(s) can't rotate due to a booger'ed up bore caused by varnish or other crap. A light pass with some brake fluid and fine 600 wet/dry sand paper and a good cleaning will remove any surface crap. I'd also not use a brake cylinder hone unless absolutely necessary as a previously run engine should not require reaming out the bores and unnecessarily gaining too much clearance. Btw, I'd also keep each lifter, if it passes the 'test', in their respective bore on re-assembly.
