@HardAlmighty If I remember this correctly, you should only need push for that area. The ones in the narrow tunnel should be accessible once you get push from one side only, but if you have pull already, maybe you went in the wrong way first and they were out of order? I do think that the path eventually leads you to the area where you use the block to get up to the echo, if I remember right, the narrow hallways lead up to that block from the back and allow you to push it down and the use it as a stepping stone on the wall to the right side of it.
