You need a shim plate. Basically, it measures the difference between the non-adjustable shim (the one with the grooves) and the top of the valve that's missing the shim. Subtract the two and you know your shim size. It's a tad bit more involved than that, but that's the gist.
Oh, and for a REALLY simple way to solve your issue: If you know your head has never been molested, take another shim from another valve, and measure it. Then go buy the same shim. Apparently (contrary to what's been taught), all shims measure the same in a virgin head. Exhaust AND Intake. (Thanks Dre!)
The shims aren't as important (size difference) than previously thought. The HLA is the "god" as far as rocker arms and shims.
