rocker arms adjustment

I have used yet another method to set the preload. If your lifters have a snap ring you can set each lifter individually by measuring the space between the snap ring and the lifter plunger using a round spark plug type feeler gauge. Start by setting the lash to zero (no longer able to spin the pushrod freely and there will be no clearance under the snap ring). Then adjust the preload and measure to the desired clearance. I have used this method. It is quite time consuming.
