Valve clearances

On the last legs of a big overhall... looking for advice on setting up the valve clearance. Looking at the FSM it talks about using shims and shim selection. However looking at the available adjustment it looks as though there is adjustment by using a flat screwdriver and open end spanner. Can anyone shed any light? It's a 4.2 1HD FTE engine.

The 1HD-T (as does the later 2L/3L and the 1KZ) and uses shims to set the valve clearances but the more modern 1HD-FT and 1HD-FTE have gone back to the older way of doing it with adjustment on the rocker - there's progress for you and good thing too, is much easier to do and do more often which has to be good for the engine.
