Note: New and remanufactured cylinder heads are commonly sold at auto parts stores. No special tools are required, so you can replace the cylinder head yourself.
1. Removing the cylinder head involves removing and disassembling the intake and exhaust valves and their associated components. If they are still installed, remove the camshaft and rocker arm assembly from the cylinder head. Label the parts or store them separately so that they can be reinstalled in their original positions.
2. Before removing the valves, also mark the valve guide bushings (photo).
After removing the valve components, store them in a plastic bag to avoid mixing them with other valve components
3. Compress the valve spring on the first valve with a spring compressor and remove the retainers (photo). Carefully release the valve spring compressor and remove the valve spring retainer, spring seat, valve stem seal, and valve. If the valve is stuck in the guide, push it back and clean the area around the guide groove with a fine file or whetstone (photo).

If the valve stem does not come out of the guide freely, lower the valve into place and file down the top of the valve stem with a small file |
4. Repeat the procedure for the remaining valves. Be sure to keep all the parts for each valve together so they will need to be reinstalled in the same place.
