The inner springs on yours are just dampers, no need to remove.

My rockers are adjustable.

Here is the way I like to do it.

Take the harmonic damper and mark TDC as zero degrees, another mark at 120 and another at 240.

Next, put engine on compression stoke TDC on #1
Adjust both valves by loosening inner lock hex bolt in poliloc. Turn nut down till pushrod begins to move lifter cup or zero lash is found by wiggling pushrod. Then turn nut in a additional 1/2-3/4 turn.
Turn engine over 1/3 revolution or to next 120 degree mark. Perform same procedure to next cylineder in firing order.

Contiue till done.
Be sure to lock all of the polilocs.
Be sure to run a jug of GM EOS in your oil for breakin.
