What exactly are the consequences of over-tightening?
From MichaelN

Oil leaks.

Take care.

he is using the angle meathod like i described except i just go by the angle of the slot in the screw. another thing, i never really losen the 13mm all the way. i put the wrench on with the screw driver, if it is too tight, i turn the nut and the screw at the same time, never losening the nut very much, then hold the screw driver still and tighten the nut and re check. if it is too lose, i hold the screw driver with a little tension turning to the right so it does not turn as i losen the nut. again, losen just enough so the screw driver will turn, then i will turn both the nut and the screw driver CCW together until the nut is tight, then re check.. you will find you dont have to losen the nut very much because as you tighten the nut, the screw will want to turn. it is easier to adjust from lose to tighter because of this.

unless you just did a rebuild, your valves should be very close and you only need fine adjustments. if you losen the nut too much or try it like wayne said, sorry wayne, you will be all day trying to get them right and get them consistant. make small changes and base them on the angle of the slot in the screw head.

i usually go through a few blades for the holder. i set mine so the gage is very hard to get in and out, but i can get it in.

i tried the back side meathod. if the motor was out of the car i would use it. it was much harder getting the gages in, especially for the intake.

i think you meant a .0025 will go and a .003 will not go. this is also known as the backside meathod.
the 0025 is a litttle harder to find. i found a set that had one at auto zone, i bought the 3 they had. i mangled the snot out of them, or as MCA said, wonky
