I'm planning on a moderate cam in the future, but as it sits now better heads is a relatively quicker swap for this car since it is my daily driver and I have a new carb in the mail anyways. Cam means taking out the radiator and water pump AND heat exchanger (AC car) which is a bit more involved.If I were in your position and going through the trouble of a head swap, I'd go just a bit deeper and add a cam to the mix. That will likely net you more power gain than a head swap. Goodwrench replacement engines have pretty lame cams.
