Pushrods stock or harden
Im changiing my heads to ones that have 918 springs, will the stock pushrods be good enough to rev to 6200 with the 918. Also I just received the heads and was wondering if something goes in the pushrod opening in the head, or is it just metal on metal. It seems as if a bushing or guide should go there but I have nothing to compare it to untill I remove the stock heads. Thanks
i never saw the point in adding aftermarket **** and seeing how much of the stock stuff you can get away with :shrug:
