Use a fine round-edge needle file to take the raised edge off so you can't feel it with a fingernail.
A little missing metal from underneath the cam is not an issue because all the force on the cam is upwards, but you don't want a raised portion of aluminium touching the cam since you won't be able to torque it properly and as soon as the cam starts spinning it will melt the aluminium, spread it all round that journal like shiny mayo, and ruin the head.
