    The spcs are...

    0.15-0.19mm (0.006-0.007 in.) on the intake side

    0.17-0.21mm (0.007-0.008 in.) on the exhaust side

    And you don't have to have the Honda tool, but you have to have something like it. B16 on here made one, and a couple others, using a box end, cutting the head off, and then rewelding it at an angle.

    The aftermarket tool is even better than the Honda one. Check out Snap-on's web site. I think the Blue-point version is about 40.00.

    I use a GearRatchet set and a screwdriver. It costs less than the Snap-On tool, is much more useful, and works every bit as well.

    and set the lash to the lower side of the reccomended specs as this will let the valve open a bit more. more lift, more power.

    me too, it wasn't nearly as hard as i thought it would be. done it to both a b-series and d-series. pretty simple and it ony took like 45 min my first time and now i am sure it would take much less.

    Make sure you lash properly I had a first timer friend over tighten and it caused it exhaust valve to stay open just enough. There was not power and no vtec. He is lucky he didn't bend the valve.
