Maximise the airflow through it, make sure there are no gaps for the air to escape around between the topmount and bonnet (use bits of foam to seal any gaps) and try to ensure the air has somewhere to go afterwards (if you dont have a lower pressure underneath the topmount you wont get any airflow at all)
Not really an easy way of doing this without using a magnehelic guage and measuring the air pressure then making undertrays and splitters etc

If you can stop the heat radiating from the cam cover but maintain airflow through the core that would be an improvment. As for directing air out the back of the bonnet i dont think you'll do very well as its a high pressure area, any scoop or vent there will just let air into the engine bay rather than let it escape

just a thought here but....
what if you raised just the back of tmic along with raising bonnet at back, both equal and by a fair bit then gettin a sheet of metal flat on tmic bracket to direct air and shield heat soak.
to be honest though seems a lot of effort when you consider how cheap fmic's are new and used.

well the only prooven mod so far iv come across is the Sard Cooling Spray.
Its a kit made by sard for hte ep82/91 which involves a kit with 2 foggers spraying water onto the topmount. It comes with its own controller, pump etc.
Sard claim it can decrease charge temps by 27%.. im not sure about this figure as its never been tested locally, though i know somebody who had tried one with pretty good results.
