First you will need the proper repair manual for your year, make and model of car. You will need to first drain the radiator coolant and remove the battery. Everything has to go on the top of the motor, fuel injection, carburetor, intake manifold etc. Next remove the exhaust manifold. Now you can remove the rockers from the head and unbolt it from the motor. Always have the head looked at by an automotive machine shop before reusing old heads. Reinstall in the reverse order using the manual to insure proper head installation.
