Do it all at once, you will spend double the money on labor if you decide later to install a cam. Its only about an extra 100-200 bucks to install a cam. Besides those heads need to breathe. Save your money, it would be good to install new pushrods that have the correct length in order to have the right valvetrain geometry. I wouldnt go with a cheaper iron head, for one they dont flow as well, and you can run more timing without detonation on an aluminum head.
