Zero Clearance valve lash ?

follow the same sequence as if you were adjusting for a solid lifter...turn the adjuster until you have zero lash then add the preload on the lifter....020 preload...

I like this chart because it follows the firing order, nice. More thorough than the 4 point adjustment!
