In case of the rocker arms are separated or isolated from the shaft, it would be wise to jot down the orientation. Then, pull out the pushrods and then set them aside so that they do not mix up during instillation, in a box that confines the pushrods. Check the rocker arm for wear, cracks and signs of damage on the contact area with the pushrods and at the valve stems and at the pivot area and at the shaft where the part creating the rocker arm replace worn or damaged part. Check that the hole at the pushrod end of each rocker arm is open and after that inspect the pushrods for the cracks and other signs of heavy wear, roll each over the flat surface, to check their bend. To reinstall, coat the lower end of each pushrod lightly with clean engine oil or moly-base grease, then return each one to its former position, being certain that it makes bottom in the lifter socket.
