Thats depressing the plugger in the hydraulic lifter about the distance of a plug gap. Comp uses this as their preload spec.
Make sure you do it cyl by cyl. Rotate the motor around by hand to get the cam lobe on the base circle. Pull a few plugs out to help turn it over.

good luck

 

Like jcb says,I did mine one at a time.
I tightened mine till there wasn't any up and down play,but I could still spin it,then I went a 1/4 turn........

 

thanx alot guys. im gonna try my best to make it come to life today. got 7 hours of sleeep
