Basically you adjust them while the valve is closed.
Pick a cylinder you wanna work on the valves. Then rotate engine clockwise, when the exhaust valve is about half way open, adjust the Intake side. Just tighten down the rocker slowly until you just feel the no up and down movement in the Pushrod. This is Zero Lash, then go another 1/4-3/8 of a turn on the adjusting Nut, then crank down on the set screw.
Same for the exhaust, except you adjust it when the intake valve is fully open.

base circle of cam, 1/2-1 turn past zero lash and lock em.. Don't be startled if they make some initial noise when you start the car up....
You don't need to do anything to your pump driveshaft, so long as the dist has been in there before???
IT doesnt go straight in because of the gears and how they need to mesh. Slowly rotate the rotor clockwise while installing and you will feel where the teeth mesh. Make sure to install ithe dist so your tfi doesnt smack into anything if you mess with timing also. Set it in the sweet spot...
