Use a magnetic-mount dial indicator touching the top of the rocker arm inline with the valve stem instead of a feeler gauge to check the clearance. If there is a dimpled rocker face the dial will reflect the true clearance instead of bridging over the feeler gauge blade.

Was going to suggest that method, but most people don't have a dial indicator (HF sells them, with a mag base for $20).
I'm sure that if you set up your indicator, you'd find that you need to turn the adjuster 1 flat (.007) to be good enough. So why not save the $20 (and the drive) and turn the adjuster 1 flat? 2 flats for exhaust.
