The cams are adjusted on a dyno to see if your adjustments are doing anything beneficial for the powerband. Start by advancing the intake cam a few degrees. It will make the idle more lopey and will help out bottom to mid range power without much sacrifice to the top end. Don't get too extreme with this as it will bring the pistons and valves closer together. After that, try retarding the exhaust cam a few degrees and see what gains that will give you. It will also lope the idle and add some mid range power.
All cars are different, so you may have to mess around with them for a while to get a decent result. You are looking for a gain across the powerband, not peak numbers in a very small range of the powerband.
Valve lash is adjusted the same way on stock cams as it is with aftermarket cams. You are measuring the non-lobed portion of the cam with the rocker arm, so it doesn't matter if the cams have small lobes or if they have huge lobes, because the measurement will still be the same.
