Ah, when you said lash, a solid cam popped into my head....

Same rules on what order you set them.

With a hydraulic cam, then just take up all the slack in the pushrod (doesn't necessarily mean that it will have drag on it or will barely turn, it just means that there is zero lash), then give her about a half turn and lock it down.

I don't use a torque wrench on the rockers, just adjust the preload, then put the smack down on the set screw with a T-handle.

If you wanted to get technical, your lifter manufacturer will have a "preload spec"...say .015-.020". If you measure each thread on your rocker stud, you will see how much a half turn, 3/4 turn, or full turn will preload the lifters. Then you can adjust accordingly.

However, unless it's a short travel lifter or I'm trying to set it at the very top of the travel, then I go about 1/2 turn past zero lash.
