Abase cylinder head is easy to obtain from dealers and auto parts stores if new or if remanufactured ones are available for most engines, and since the home mechanic may not have the expertise to recondition the head once separated into various parts due to the lack of appropriate equipment of necessary gaskets and, in some cases, the parts may be unavailable as well to be used to rebuild the head, getting a new or remanufactured head Start with supporting the head on 2 wooden blocks so that it does not roll and placing the valve lifters and their shims in a safe where they will not get lost; identify and remove the lifters using string and a felt pen in such a way that they will end up in a clean and protected box or better still, taped in plastic bags to avoid mixing them up. Before doing away with the valves cut a box or label plastic bags for storing the valves plus other related components in a way that they will not be mixed up because they are supposed to be reinserted in a certain order. If necessary, loosen the spring nut and remove the keepers and with the help of a spring compressor, remove the spring retainer, the spring, and seat; then remove the old oil seal and valve from the head; if you find out that it is tight, use a file and smooth the keeper groove. The same process should be followed for each valve although the check valve lifter and spring will be retained separately for reinstallation of the parts. Once all the valves and the components are detached and set aside for storage, clean and scrutinize the head ;If an overhaul of the engines is being done then other procedures when doing the cylinder head cleaning and inspection should be followed.

Do not tilt the head on its side or turn it upside down while the valve lifters and shims are still installed, as they may fall out and get mixed up.

Thorough cleaning of the cylinder head and related valve train components, followed by a detailed inspection, will enable you to decide how much valve service work must be done during the engine overhaul.

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.
