It was in the late 70,s or very early 80,s

Do you have any other information like a scene or character?

I'll throw Deliverence out there because even though it was early 1970's it might fit and it's a place to start.

There is a scene when a guy finds his buddies head on a stick and another where a man is burned over a fire I think maybe something about the windigo??
