Re: LT1 Valve adjustments

While this 8-step indexing procedure for adjusting the lifter on the base circle of the cam can be applied - in principle - to any solid-lifter cam, the actual lash dimension required to implement the procedure varies with the height and length of the cam clearance ramps and the as-measured, functional rocker arm ratio (not the nominal value).

So you can adjust the valves using the indexing procedure for any solid lifter cam... but you need to use the lash settings supplied with the cam... unless you go through the sequence to determine the correct cold lash clearances and actual rocker arm ratio.
