do i absolutley have to check the clearence for all the rocker arms or can i just do them in the specific order they go by? what is the easiest way to set these? they already should be clearenced i thought. its a kit for my car only. a 95 Z28. the sooner the better thanks.

 

you have to through and do each rocker in the sequence that it tell you to. two 180deg rotations.

 

TDC on each compression stroke.

 

Each rocker gets set. http://shbox.com/1/4th_gen_tech2.html#adjust_valves
