If you are replacing head gaskets or rebuilding your 6.0L or 6.4L Power Stroke, you might find wear marks or grooves worn into your original pushrods. This is caused by pushrod to head gasket contact. It is best to replace all of them as these wear marks create a weak spot which could cause major problems later.
