I was told that my engine head was too pitted to.

Hello you didn't specify your Civic model or engine size. However, yes the head can be at a point it can't be repaired. If you doubt that then the best thing is to take it to another machine shop for a second opinion. Also, AutoZone sells complete heads for that model or shop around. I know those heads come with valves etc already installed. You just transfer any external components and make sure plugs are in or out in the correct spots.
