When adjusting your valve clearances, what determines the specs you adjust them to?

Is it the camshaft you're using, or the valvetrain(valve springs/retainers) you're using?

Example, I want to install a JG Engine Dynamics camshaft into my car while using the stock valvesprings/retainers because I'm not going to rev over the stock rev limit. Should I adjust the valves to the stock specs (or on the tighter side of stock) or are their specs that the manufacturer supplies?

TIA.
