My IAC motor works and I clean it well every month, my question is very simple , how should I adjust it, what is the perfect adjustment for a discovery 1995 ?

i`m a very simple person so please try to answer me in a simple way such as how many cm or mm should the head be protruding exactly so I get the best performance .

No adjustment's are possible .. just cleaning or replacing the valve !

IDLE AIR CONTROL VALVE
Removal & Installation
Disconnect battery negative terminal. Remove connector from Idle Air Control (IAC) valve. See Fig. 14 . Unscrew valve from its location at rear of plenum chamber. Remove sealing washer.
To install, fit a NEW sealing washer.
NOTE:If same bypass valve is being refitted clean any previous sealing compounds from threads. Apply Loctite 241 to threads of valve before reassembly.
