The remaining steps follow the reverse order of removal. Finally, add coolant, change the engine oil and filter, start the engine, and check for proper operation and any leaks.

Unbolt the exhaust pipes from the manifolds.

Check the mating surfaces for damage, using emery cloth for slight imperfections and considering machining for excessive damage.

Before installation, ensure perfectly clean mating surfaces between the cylinder head and block, free from carbon, old gasket material, and oil residues. Cleaning with a gasket scraper and lacquer thinner or acetone is recommended.

To install the heads, ensure the mating surfaces are clean and free from old gasket material and dirt. Use a gasket scraper and brake cleaner to clean the surfaces. Check for any damage and remove it if necessary. Chase the threads in the head bolt holes and clean the bolt threads.

Before starting, disconnect the batteries' negative terminals and drain the coolant.

Depending on the cylinder head, you may need to remove other components like the alternator, transmission and oil dipstick tube, air conditioning compressor, or heater core tube. Additionally, the timing chain cover should be removed, and the crankshaft should be rotated to Top Dead Center (TDC).

After loosening the cylinder head bolts, you can lift the cylinder head off the block.

Block cylinders should be stuffed with clean shop rags to prevent debris from falling in, with a vacuum cleaner used to remove any material that enters.

Remove the intake manifold and the exhaust manifolds from the cylinder heads. Also, remove the steering pump mounting bolts and move the pump aside.

Remove the banjo bolt, sealing washers, and the fuel line from the rear of the head, then remove the fuel injectors. Remove the rocker housing and gasket. Loosen the head bolts in the reverse order of the tightening sequence, inserting each removed bolt into a cardboard template to keep track. Carefully pry between the head and block to break the gasket seal, then lift off the cylinder head, either with an assistant or using an engine lifting hoist. Inspect the head and remove any wiring harnesses or ground cables still attached.
