Tools and Materials Needed:

- Socket set

- Wrench set

- Screwdriver set

- Tappet wrench

- Gasket scraper

- New cylinder heads

- New head gaskets

- Intake manifold gaskets

- Exhaust manifold gaskets

- Valve cover gaskets

Step-by-Step Guide:

Step 1: Disconnect the Battery

- Disconnect the negative terminal of the battery to avoid electrical accidents while working on the engine.

Step 2: Drain the Coolant

- Locate the radiator drain plug and open it to drain the coolant from the engine.

Step 3: Remove the Valve Covers

- Remove the valve covers using the appropriate wrench or screwdriver to expose the cylinder heads.

Step 4: Remove the Exhaust Manifolds

- Remove the exhaust manifolds by unbolting them from the cylinder heads. Make sure to place a gasket scraper under the exhaust manifolds to prevent the bolts from falling into the engine.

Step 5: Remove the Intake Manifold

- Remove the intake manifold by unbolting it from the cylinder heads. As with the exhaust manifolds, use a gasket scraper to catch any bolts that fall.

Step 6: Remove the Rocker Arms

- Remove the rocker arms and pushrods by using the tappet wrench. Organize the parts carefully so they can be easily reinstalled later.

Step 7: Remove the Cylinder Head Bolts

- Remove the cylinder head bolts using the appropriate wrench. Be sure to follow the correct bolt sequence to avoid uneven stress on the cylinder heads.

Step 8: Lift the Cylinder Heads

- Carefully lift the cylinder heads off the engine block. Be cautious not to drop them as they are heavy.

Step 9: Clean the Cylinder Head Surfaces

- Clean the mating surfaces of both the cylinder heads and the engine block using a gasket scraper to remove any remnants of the old head gaskets. Make sure the surfaces are clean and smooth before installing the new gaskets.

Step 10: Install New Head Gaskets

- Install the new cylinder head gaskets on the cylinder heads. Make sure the gaskets are properly seated and oriented.

Step 11: Install the Cylinder Heads

- Place the cylinder heads back on the engine block, making sure to align the head gaskets correctly.

Step 12: Install the Cylinder Head Bolts

- Install the cylinder head bolts and tighten them in the proper sequence to the manufacturer's specified torque settings.

Step 13: Reinstall the Rocker Arms and Pushrods

- Reinstall the rocker arms and pushrods using the tappet wrench. Make sure to set the appropriate valve clearances.

Step 14: Reinstall the Intake Manifold

- Reinstall the intake manifold and secure it with the appropriate bolts.

Step 15: Reinstall the Exhaust Manifolds

- Reinstall the exhaust manifolds and tighten the bolts securely.

Step 16: Reinstall the Valve Covers

- Reinstall the valve covers and tighten the bolts to secure them.

Step 17: Refill the Coolant

- Refill the radiator or coolant reservoir with the appropriate amount and type of coolant.

Step 18: Reconnect the Battery

- Reconnect the negative terminal of the battery to restore electrical power to the vehicle.

Note: Always follow the manufacturer's recommended procedures and specifications when working on any vehicle. If you are unfamiliar with engine work or uncomfortable performing these steps, it is best to consult a professional mechanic for assistance.
