Here's how I do a 4 cylinder engine. With No. 1 at TDC on compression stroke, you can set valve lash on both intake and exhaust of No. 1. You can also set either the intake, or the exhaust, on No. 2 and 3 (you can tell which by where there is lash). Then roll the engine over 360 degrees until No. 4 is on TDC compression stroke. Now you can set both valves on No. 4, and the other valve on No. 2 and 3 from what you set when No. 1 was on TDC compression stroke (again, you can tell which one has lash on 2 and 3).
I'm sure there are other ways, but with this method you can do all the valves with just two positions of the crank.
