87GN,
Have you put a 4" bock under the nose of the hood, then have an assistant push down on rear of the hood while you loosen the hinge bolts until the rear edge of the hood makes contact with the cowl seal at the center? You need to do this prior to reattaching the hinge springs. That procedure takes out the slack in the rivets of the hinges, allowing the hood to close properly with the springs installed.
