You are measuring the gap between the top of the valve and the pad on the rocker which contacts with the top of the valve (with a feeler gauge). When the valve is shut, the rocker should be completely free of it, that's the gap you're measuring.

Bear in mind that you're likely to have a degree of wear on the rockers, they tend to develop a little pocket where they contact the valve.

Don't be tempted to set the clearances a bit tight, the valves on a B18/B20 should be slightly chattery. Too tight = burnt out valve in the long term.
