    what kinda prob did u have to make u pull the heads ???? i run a drag car with almost the same engine ,,, but i do not run any type of water in it ,, except for cooling the heads ,,, but that is another thing ,, u can surface them many times ,,, as long as they don't have any cracks in them ,,, but more info would be good :approve: :approve: :cool: :cool:
    But if u do have to have them surfaced ,, u must also have the intake mainfold surfaced to the same specs ,,, cause the angle changes where the intake mounts :approve: :approve: :approve:
