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

And .017 is way too loose. If you think about it, with bronze guides I set the exhaust clearance at .003. That means .017 would be almost 6 times the clearance.

With cast guides you can use .0025 clearance.

But.... follow me before you correct me :D ........ Your tolerances are to make "better than new". Your a machinist that cares and takes pride in your work, no expenses barred. So, this may be very difficult for one such as yourself. However, picture a guy at home, that pulls the heads off, shall we say, to install new exhaust valves and lap all valves, or perhaps some home porting, wouldn't .017 be "acceptable" for this type of build?
