I would adjust them one cylinder at a time just like comp cam suggests. Mopar had a lash setting chart. I used to do it by the chart however they claim cam profiles have changed and you need to be sure you are setting the lash on the base circle of the cam. This should be your lifters and instructions.Adjustment
Ok, I will stay with the Comp instructions and do one cylinder at a time like I have been. Finding the thread pitch on the adjusters is first thing tomorrow.
