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

Reviving this thread for some help. I have a pair of "new" EQ heads. Actually they had about 3 dyno runs on them. When I pulled the springs I found a badly bent exh valve. There were no contact marks on the valve. I chucked the rest of valves in my drill press and mic the valve face. I found 3 exh and 4 intake with very slight bend (.010 runout) even though they seat OK (no light shines through). I'll replace those. I have no idea what the cause was. On a recent post I have read that valve guide clearance should be checked for tightness on all new heads. Thinking this was the cause I tried a wobble test and I'm getting .005 on the intake and .006 on exhaust with the valves held about 1/2 inch off of the seat. This seems good to me as far as not being too tight. All valves slide freely in their guides. I'm tight on funds otherwise I would take another trip to the machine shop plus waiting a few more weeks. What do you guys think?
