    Do you mean is it necessary to replace the clyinder head bolts - the answer is 'yes', because the older head bolts have elongated (stretched) when installed and torqued during the original or previous assembly of the cylinder head to the engine block.
    The bolt elongation (or stretch) is a normal consequence of threaded fasteners being torqued and the condition is desired to apply the clamp load of the bolts to properly seal the clyinder head to the engine block, and to insure correct heat transfer.

    The new cylinder head bolts as a cost of the overall repair - are inexpensive when compared to having an old head bolt fail during the engine service - and the damage and repair headache this might cause.

    Check the many on-line auto parts sources, such as; www.autopartswarehouse, or www.rockauto.com for the replacement parts. For example, they (RockAuto) list the replacement cylinder head bolts in a complete kit from around $12.30 for your vehicle. Cheap insurance indeed!
