Is there some kind of trick to getting the valves adjusted perfect on a '96 Acura Integra?

I own a '96 Acura Integra LS Auto. I've adjusted the valves around 10 times now and I still can't get it right. I adjust them cold, to spec using feeler gauges as called for by the Acuras repair manual, but they still click. Whats the deal, is there some kind of trick to doing it?|||Are they out of adjustment when you check them? You could very well have other parts that are worn causing your problems...
