Regardless of whether or not the head was sent to an automotive repair shop for valve servicing, make sure it's clean before beginning reassembly. If the head was sent out for valve servicing, the valves and related components will already be in place. On all engines, lubricate and install the valves, then install new seals on each of the valve guides. Using a hammer and deep socket, gently tap each seal into place until it's seated on the guide. On OHC engines, reinstall the valve lifters. Beginning at one end of the head, lubricate and install the first valve. Apply moly-base grease or clean engine oil to the valve stem. Drop the spring seat or shim(s) over the valve guide and set the valve spring, retainer (or rotator) and sleeve (if used) in place. Apply a small dab of grease to each keeper to hold it in place. Compress the springs with a valve spring compressor and carefully install the keepers in the upper groove, then slowly release the compressor and make sure the keepers seat properly. Repeat the procedure for the remaining valves. Be sure to return the components to their original locations - don't mix them up! Check the installed valve spring height with a ruler graduated in 1/32-lnch increments or a dial caliper. If the head was sent out for service work, the installed height should be correct. The measurement is taken from the top of each spring seat or shim(s) to the bottom of the retainer. If the height is greater than the figure, shims can be added under the springs to correct it. Caution: Don't, under any circumstances, shim the springs to the point where the installed height is less than specified. Apply moly-base grease to the rocker arm faces and the fulcrums, then install the rocker arms and fulcrums on the cylinder head studs.

The cylinder head cleaning and inspection process should be started after the complete engine overhaul procedures have been finished.

The fuel line needs to be detached from the clip at the front of the right cylinder head if applicable.

Keep all the parts for each valve together so they can be reinstalled in the same locations.

A required camshaft holding fixture should be used to lock the camshafts in place, and these fixtures should be left in place until after reassembly is complete.

Use a tap of the correct size to chase the threads, as dirt, corrosion, sealant, and damaged threads will affect torque readings.

Make sure the head is clean before beginning reassembly.

Check the spring retainers (or rotators) and keepers for obvious wear and cracks. Any questionable parts should be replaced with new ones, as extensive damage will occur if they fail during engine operation. Make sure the rotators operate smoothly with no binding or excessive play.

Examine pushrod ends for scuffing and bending, check rocker arm studs for damaged threads, and clean cam followers (for OHC engines), inspecting their pads and rollers, and replacing worn or damaged components.

Remove the intake manifold.

Lift the head(s) off the engine. If resistance is felt, DO NOT pry between the head and block. To dislodge the head, place a block of wood against the end of it and strike the wood block with a hammer. Store the heads on blocks of wood to prevent damage to the gasket sealing surfaces.

Lift the head(s) off the engine, breaking the gasket bond if necessary by placing a wood block on the head and striking it with a hammer. Store the heads on wood blocks to prevent damage to the gasket sealing surfaces.

The valve seal has the spring seat/shim incorporated into one piece. Make sure replacement parts are the same as the ones removed earlier.

Run an appropriate size tap into each of the threaded holes to remove corrosion and thread sealant that may be present. If compressed air is available, use it to clear the holes of debris produced by this operation.

Cylinder head removal is a difficult and time-consuming job that requires several special tools. It is recommended to read through the procedure and obtain the necessary tools before beginning.

If the valve binds in the guide, push it back into the head and deburr the area around the keeper groove with a fine file or whetstone.

Store the cylinder heads on blocks of wood to prevent damage to the gasket sealing surfaces and avoid sliding them across surfaces to prevent gouging.

On V8 engines, reinstall the valve lifters.

Measure the margin width on each valve, ensuring it meets specifications; any valve with a margin narrower than 1/32-inch must be replaced.

The first step involves the removal of the intake and exhaust valves and related components, including the rocker arm nuts, pivot balls, and rocker arms from the cylinder head studs.
