Hi Bill, The wire is likely left over from the casting of the heads. No big deal. Leave them or take them out. The rocker shaft slides out of the head and each rocker arm goes on individually. You remove the shaft by pulling the small pin on one of the rocker shaft journals. As you slide the rocker shaft out, the rockers and spacer springs will come off. Keep track of the order and shoot photos of the heads for reference. K.
