I know you don't have to adjust the lifters with the cadillac set up , but say on a small block chevy , I watched a guy adjust the lifter push rods ,He said it doesn't matter where you start as to where the cam is . You go around in line and take all the slack out of each rocker , rotate engine 90 degrees and repeat by adjusting any loose rockers . Rotate 90 degrees again and repeat . 90 degrees and repeat . only adjust the rockers that the push rod has verticle play . He said this works on any engine with hydraulic lifters . then turn down each adusting nut on the rockers 1/2 to 3/4 turn and you are done . Have you ever did it this way ? Thanks , Bob
