2. Alternately, starting from the edge of the head, lubricate and install the valves. Lubricate valve stems with molybdenum based grease or clean engine oil (see fig.9.2). If you are installing already working valves, insert them into place. If you are inserting new valves, insert each valve in the position it was lapped in.
3. Install the plastic protectors supplied with the lower spring seat/stem collar onto the end of the valve stem. Then fit a new cuff without distortions on the top of the guide and leave it in this position. When installing the valve spring, it will press the lower seat / stem collar into place with its own force (see fig. 9.3).
4. Install the spring and upper valve seat (see fig. 9.4, a, b).
5. Compress the spring with a compressor to compress the valve springs and carefully insert the crackers into the groove of the stem. If necessary, apply some grease to hold the biscuits in place (see fig. 9.5, a, b). Slowly release the compressor and check that the biscuits are seated in place.
6. After installing the valve, place the head of the block on a workbench and tap the end of the stem with a hammer through a block of wood to install the valve components.
7. Repeat the procedure for the rest of the valves, installing the components in their places.
8. Install hydraulic valve clearance adjusters (chapter 2A or 2B).
