You can't carbon date rocks. Carbon dating measures the current amount of Carbon 14, which is a radioactive isotope with a fairly long half life, and compares that to a projected initial carbon 14 measurement.
Carbon 14 is present in organic material, inorganic material may have carbon 14 but it is basically impossible to know the starting amount. In any event a carbon date of a rock, if you could do so, would tell you when it was formed, not when it was carved. The rock, is obviously much older than 1k years, and even older than 60k years, possibly millions of years old.
Most rock formations are dated with measuring erosion from wind and rain. We have a fairly good idea of how different types of stone are eroded. Afaik this type of analysis has never been done on the easter island heads, and it is assumed they are less than 1k years old and made by the previous island inhabitants, the Rapa Nui. Never mind how a primitive island culture with low population could move 40 ton statues 20-40 ft tall up a mountain.
