valve clearance

I have a 95 Integra and want to adjust the valve clearance. I heard you need a special tool. Can anyone tell me where I can get the tool?... ( tried Snap-on ) I would also appreciate any advice from someone who has already been there.

why do you want to adjust your clearance are your valves tapping. Anyhow what you need it a open center socket set. I hot mine from lowes. Its a racket with a big hole in the center so you can stick a screw driver in it to hold the adjuster nut still while you lock it down
