Re: adjusting LS1 rockers
Simple. Make sure the rocker is seated squarely on the valve, tighten it to 22 lb ft. and that's it. They are adjustment free.

Re: adjusting LS1 rockers
Jabroni, i guess that 22lb.ft is with stock cam and the stock rockers how about if i go with aftermarket performance cam or aftermarket roller rockers, there should be an offset compared to the stock cam and/or stock rockers, and that offset requires adjusting just like LT1's, isn't that right? thanks.

Re: adjusting LS1 rockers
Ditto...
An LT1 uses an adjustable rocker arm, and you do have to adjust lifter preload.
The LS1 uses a non-adjustable pedestal mount rocker. Torque it to the required 22ft-lbs.
If you have made changes which throw off the valvetrain geometry or lifter preload, you'll have to change pushrods or shim the rocker pedestals to correct it.
...or you could lay out the $$$ for Crane 1.8 roller rockers, which are adjustable.
