They can be challenging. It takes extreme dexterity and patience. If the header bolt is yoo long to fit in the hole, use a shorter bolt, like 3/4" not 1". You may need to use an angle wrench, where the openeing is offset to the side. You may be able to get them from the bottom side of the car, jack it up and get underneith it. Use your other hand sometimes. If there is NO ROOM get the engine hoist, hang the motor, disconnect the motor mounts, and push the engine over to gain the room. You'll also want to replace the exhaust gasket at this time; as the gasket around the port in question has been burned up. if you cac hear and feel the exhaust leak, the gsaket is wasted. don't completely remove the first and last bolt campletely, Just loosen them. The new gaskets will have notches to slide them in.
