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

Here's what the FSM has to say. They use .017" as the service limit. I wonder how tall the official positioning tool is.

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.
