Does any one know of a reputable shop that will rebuild the head for my 2006 WRX at a reasonable price in the greater Atlanta area, preferably northeast perimeter. I have pulled them off the engine and can deliver. What is a reasonable price for a rebuild with a resurfacing. Is a rebuild something I can do my self. I am pretty sure I have a bad exhaust valve, could I just put new valve stems and what ever other parts come with a head rebuild kit and call it a day, or should I leave this job to a professional?
