please help! i dont know how to adjust my rocker arms

Be sure each pair you're installing has the lifters on the base circle of the cam. Tighten the rocker until there is zero lash - til it just reaches no gap on the pushrod or valve stem side. From that point turn the nut another 1/2 to 3/4 turns, and then set the allen lock nut. Rotate the engine so the next pair is on the base circle of the cam - and repeat. If you follow the firing order, you'll minimize the amount of hand turning of the engine you have to do.
