Sometimes I take a bearing knife and cut the shiny spot off until it turns free and sometimes I just run it. I've never had a bad experience, and some of them I thought were way too tight.

If you know where the spot is... clearance it.. it should spin freely with just using your hand and spin a few turns

Make yourself a reamer by making diagonal hacksaw cuts in each bearing journal of an old cam.

because scotchbrite is an abrasive and will leave minute particles of that abrasive in the bearing surface also you will need to wash the block out again if you haven't already done so,,a bearing knife is the proper way.
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

I thought it had to be bent some to not rotate freely. I have heard of some people straightening them with a hammer and a dull chisel, NOT ME though You should be good, I have had to scrape more than one new cam bearing due to Mopars poor machining of the cam tunnel not getting one or more of them not the proper I.D. One of the better machine shops I use to use in SO CA would use a small cylinder hone to enlarge them
