Adjust valves

I rebuilt a 66 273 and put a comp. cam in it solid lift but i have never had one with the solid lifters and i don't know how to adjust them,I would like to do it before i put the motor in my car and i need someone to walk me through what i need to do to adjust them.I don't want to ruin a new cam on start up.I have a diagram but don't understand it .The lash on it is 16 on intake and 18 on exhaust.Thanks for any help....
