The price will reflect what needs to be done for the repair. Will the heads be sent out to the machine shop? Are they cracked and need replacment? Are you supplying your own parts? There are many options and different ways to handle the repair. I suggest a second opinion before putting big bucks into the repair. Unless the car has personal value, the cost of repair might outweigh the cars resale value.
