Giving a detailed description in this forum may be difficult. The best
thing you could do is go to the book store and buy a good repair manual if
posible a factory repair manul for the year and model....
Adjusting valves are not really hard...but they do require precision. And
it is also something that seems much simplier after you watch someone do
it....

Rule of thumb was tighten rocker while rotating push rod between thumb &
forefinger, when you cannot rotate pushrod, go 1 full turn. tighten rocker
slowly pressure changes quickly.

Do you want the easiest way or the cleanest way?
(assuming hydraulic valves)
The easiest way is to take off 1 valve cover, and you can buy things that
clip on the end of the rocker to divert the oil. Start the engine, and
back the rocker nut off until you hear a light tick on that cylinder. Then
turn it in slowly until the tick goes away, and then turn it an additional
3/4 to 1 turn (this is preloading it, half a turn will probably be plent,
but you may have to adjust them in a couple of years).
The clean way is to take off all valve covers, and remove coil wire. Crank
the engine until you see a valve begin to depress. At this time, the
corresponding valve on that same cylinder is completely off cam. At this
time you can adjust that valve. For example, if you crank it and the
intake valve begins to open, you know that the exhaust valve is completely
shut and you can adjust it. Adjust it by loosening rocker nut, and slowly
tighten it until you can't turn the push rod anymore (because it is wedged
between the rocker and lifter). Then turn it an additional preload (3/4 to
1 turn, etc.). Mark the valve you did and keep cranking the motor until
all the valve are done (I mark them with chalk).
Any questions write back.
If the engine pops when you are done you got a valve too tight, but if you
follow these instructions that won't happen (assuming all your lifters are
pumped up and functioning properly).

That's my webshots, with 1 pic of the corvair and pics of other stuff i've
been working on. I have z28 rims on it now, it looks real good with a high
quality photo. This spring i'll get some good pics of it. Thanks to the
corvair, I consider myself a master of adjusting valves. :banghead:
