How Can I Remove the Bony Lumps That Formed After Hitting My Head Years Ago?

It is possible to have the bone rasped down.  I think a bigger issue is whether you have body dysmorphic disorder(BDD) or not.  The bumps you are showing are subtle.  They are generally not something that would be considered disfiguring by most.  So here is the test.  How many hours a day to you think about these bumps.  If you think about it for hours a day or are preoccupied by these thoughts, this would be consistent with BDD.  Do you avoid social situations because you believe that others are talking about or making jokes about you because of these issues.  This is also consistent with BDD.  BDD does benefit from psychotherapy although my experience is that most consulting the cosmetic surgeon who have BDD are much more interested in having cosmetic surgery than psychotherapy.  It is critical that your cosmetic surgeon clearly understands your concern before undertaking surgery on this and less is more.

The calcifications that you mention are similar to frontal bone osteomas. These can be rasped chisled or burred down. The closer the skin incision is to the target the easier it is for the surgeon. Specialized equipment is needed and therefore it is difficult without seeing them to predict costs. Removing them is purely elective
