Reassembling a 2006 Outback EJ25 SOHC head.  Need to know more about the setup of the AVCS mechanism. 

Document directs to remove bolts "i" and "j" during removal of rocker assembly.   Why remove bolts????  Did so dutifully on one head and did not on the other.  Subaru dealer mechanic said he does not remove them.  Upon reassembly all parts appear to be correct to each other.  Document shows using a tool to set the spring stopper.  Don't think my parts ever got out of engagement.

Is there any adjustment needed to make sure that the clamping on the shaft when re-torqueing those bolts?

Your engine has AVLS.  Active Valve Lift System.  Only affects one of the 2 intake valves on each cyl.  Keeps the one valve lift low at low throttle, opens it full lift during heavy throttle.   (AVCS is on DOHC turbo motors and controls valve timing, not lift amounts.)

At any rate.  Do not mess with the AVLS components.

For reassembly, simply flip the spring to it's "unloaded" state.  After bolting in the rocker arms, a flathead screwdriver can be used to flip the spring end back under the little post that holds it.

Be carefull to not lose the small cylindrical interlocks and the spring under them.

They should be "messed with" if necessary to clean them of engine failure debris. They should be fully dissasembled and cleaned of all metal and old oil.

true

I was assuming this was just a HG job.

Yeah we usually don't in the case of basic HG replacement. But we do see a fair number of short block replacements also.
