Where would I find?????????

just on a whim I did a google search and like the third selection down I found this:

http://www.armorcast.com/terraform/Statues.html

an armor site with them for sale.. didn't look too much into it but what Foster said would probably work easier and be more realistic...

And I think Testors put that kit out some time in the mid or late 70's possibly... I remember seeing the Area 51 thing on the front and how it was supposed to be some secret government project and was actually flying etc... it stuck around awhile because I seem to recall seeing on the shelf when I was stationed in Wash DC at the LHS mid to late 80's...

Since no two Easter Island heads are exactly alike, I would go with making them yourself to the proper scale for the kit. It shouldn't be too difficult. The heads are extremely pitted and weathered so perfection is definitely not needed and there are literally thousands of pictures available to use as reference.

I also doubt that you will find replica heads in any scale.
