Steel metal shavings on the drain plug should go away after a couple thousand miles in a rebuilt motor.

If you see them every time you change the oil it can be a sign that the cam cam thrust plate shim set is wrong and the cam sprockets are not aligned correctly to the intermediate shaft.
If thats so then the inside edge of the chain links rub on the sides of the idler sprocket, cam sprocket, and intermediate shaft sprocket teeth as they rotate and scrape little bits of steel off the sides of them.

You can see if thats been happening by looking for excess wear on the sides of the idler sprocket and cam sprocket teeth when you take the chain case covers off.

A little magnetic paste like sludge stuck to the magnets is usually normal, but continuos shavings are not good.

There's also a chance the motor had a major failure in the past and someone didn't flush out the oil lines and coolers when they rebuilt it and the stuff in the coolers and lines is still moving around with oil flow.
