So right now i have all the rockers and pushrods out. I wanted to check every one of them before i reassembled everything. Good thing i did because there were like 5 rockers that were really loose. So Now do i just set all the rockers on without the nut and bring each cylinder to tdc and tighten? Ive never done this before and i want to make sure i dont screw anything up. with the piston at tdc thats when i tighten both rockers down?

oh and is there a more accurate way to tell if its exactly at tdc besides sticking a screwdriver in there?
