Specialized tools are necessary for disassembly and inspection of the cylinder head.

Clean all valve springs, keepers, and retainers one at a time to avoid mixing parts, and scrape off heavy deposits from the valves before using a motorized wire brush for remaining deposits.

No, removal of the cylinder head does not require the camshaft to be removed, so you may skip the steps related to camshaft removal if only the head is being taken off.

Install the springs with the painted side next to the retainer. Use a valve compressor tool to compress the spring and install the keepers, ensuring the retainer does not touch the seal.

The camshaft end play can be checked using a dial indicator or a feeler gauge. If using a feeler gauge, gently pry the camshaft toward the front of the engine and slip the gauge between the flange and the front bearing cap, comparing the measured end play to the specifications. If using a dial indicator, mount it at the front of the engine with the indicator stem touching the end of the camshaft, zero the indicator after prying the camshaft forward, then pry it in the opposite direction and observe the needle movement to determine the end play, comparing the reading to the specifications.

Use a spring compressor to compress the valve springs on the first valve, then remove the keepers, and carefully release the compressor to take out the retainer, springs, valve stem seal, spring seat, and valve from the head.

Decarbonizing chemicals can be useful for cleaning but should be handled with caution according to the instructions provided.

Remove the cylinder head along with the gasket.

The negative cable should be disconnected from the battery.

Lubricate the valve lash adjusters with engine oil and insert them into the bores, then lightly lubricate the contact points of the valve stems and lash adjusters with assembly lube.

Measure the valve stem-to-valve guide clearance with a dial indicator, and if there are doubts about the condition of the valve guides, further checks should be done by a machine shop.

Consult an automotive machine shop for repairs or obtain a new cylinder head if repair is not feasible.

If the height exceeds specified limits, shims can be added under the springs to correct it, but do not shim the springs to the point where the installed height is less than specified.

Finally, double-check the installed valve spring height; if it was correct before disassembly, it should still be within the specified limits, measured from the bottom of the spring to the upper edge of the spring retainer.

It is important to label and store parts separately for reinstallation in their original locations. Before removing the valves, label and store them with their components to keep them organized.

The remaining installation steps are the reverse of removal. Finally, add coolant, change the engine oil and filter, then start the engine and check for oil and coolant leaks.

Inspect for damage, using a file for slight imperfections or considering machining for excessive damage.
