Curious, how do YOU check valve guides with the "wiggle" test?

On my last set of EQ heads I bought ("out of the box/ ready to install" Bull$#!t!!!) they did the guides too tight, had #4 exhaust valve hang open and kiss the piston, bend valve. less than 3 hours run time and 6 miles after install. Id save the "wiggle test" for the old school machinist that has been doing headwork for a few years or more.
