This is kinda what my head looks like http://www.ericgorr.com/images/smashed.jpg I think i am going to take it to my career center and see if we can take the marks out of it.

 

Is the picture of your piston? If I understand you it isn't and your head is in need of work, but your piston is okay. You need to have a good shop do this work. If the angle from the dome to the edge of the cylinder is altered, it can greatly affect power and can also cause burnt pistons. Also if any material is removed, then it should be shaved in order to get compression back to normal. If someone who don't know what they are doing performs the work, you might be buying a new head and other parts.
