Timing Chain Cover Replacement

You can just install the water-pump and timing cover at the same time. Especially when using a new cover, you will need very little gasket sealer. The timing cover will self center unlike some modern engines that use a crank driven oil pump. On the modern engines shims are used to center the cover on the crank snout. Not used on the older type engines. Just make sure to use a sealer designed to be used in water for the water pump bolts that go into the water jackets in the block.
