The LS6 PCV setup is a big improvement, also since you have access you should do the TSB on the knock sensors where you seal them with RTV as shown further down in this:

Shocks are a wear and tear item though, and the DeCarbons sucked brand new much less 24 years old with some 30K miles on them.  Actually on later SLP cars Bilstein shocks were standard, and you could keep the DeCarbons should you go to sell it.  It'll handle and ride a lot better with the Bilsteins, but if you aren't going to be driving it through back roads and mountains spiritedly I guess it really doesn't matter.

The '93-97 base/Formula in black looks so good, why I can't convince myself to sell mine even though I can't really drive it anymore.

So, stuff continues to go back -on- the motor.
Here's the LS6 Valley Pan/PCV kit I installed....

It comes with (just about) everything...Bolts, gaskets(cover and knock sensors), a plug to block off the left side valve cover PCV outlet, and a hose to connect the new foul air outlet to the intake manifold.  The only thing it didn't have was something to block the old, no longer used, foul air outlet on the right side valve cover(the little 'nipple' on top rear of the valve cover).   

Here's the LS1 and LS6 Valley Pan you can see the box in the LS6 Valley Pan that includes the PCV Valve and some sort of separator chumpy...

On top, the main difference is the new PCV outlet that comes up next to the throttle body

My understanding is that not -all- LS6 Valley Pans have the built in PCV 'valve'.  They all have the box, but not all those boxes include the valve.
Based on what I've read this is an improvement over the LS1 set up because the 'foul' air is drawn from the valley vs. the valve/rocker area (where there's more oil splashing around).  And, the little box does some separating of the oil from the air.  It's not a 'fix' though...You can still get some oil consumption, but it should be less.   Additionally, you lose most of the external PCV hoses from the LS1 set up, so it looks 'cleaner'.

After trimming that piece in the valley (on page 4), it installs just like the LS1 cover.  The only thing that surprised me, which I didn't see mentioned
anywhere was that the new PCV outlet interferes with the  'vapor vent tube' (Aka Coolant Cross over tubes) a little.

It just took a little eyeballing and tweeking of the vent tubes with a tube bender to get around it.  Not a big deal.

Aside from that job, I got the valve cover ('Rocker arm Covers' in the GM manual) installed with new gaskets.
Careful installing new grommets on the valve cover bolts.  Before I took a shot at it I saw a suggestion to heat them in the oven around 200 deg. for 10 minutes or so...That worked OK for me, but still...literally the last one, #8 of 8 broke as I was sliding it on.  Cost me 12 bucks and a trip to the parts store.
Also installed new knock sensors.

As I mentioned, we had a bit of time before I could order parts again, so we cleaned some stuff up and took time to paint some parts.
I decided to go with red and black.  It's sort of cliche' or whatever, but the car will be red and black, and they are my favorite colors so....

I'll be painting the intake black too.

So, things are moving forward and the motor's going back together.  I have a long parts list of sensors, gaskets, brackets, adapters,  and 100 other little things. Oh, the 'hundred little things' reminds me...I found a Loctite PDF catalog that translates the various OE Part numbers for sealants and thread locker to their retail equivalent. I thought that was a cool find, I didn't know such a thing existed.  So, some of those recommended sealants and whatnot from the GM Service Manual are on the parts list too.  Here's a link to the document on Loctite's website:

This weekend I should be able to get a good order together.  In the mean time, I need to clear out the pile of parts taken off the engine, go through them and get them out of the garage to make room for new parts coming in.  Part of working in such a small area.

Thanks for checking in.

-Take Care

if you had the HA rear bar on without the front bar it will oversteer, you may find that keeping rubber bushings in the rear bar even with the HA front bar will make the car more neutral.

I did keep the rear bushings rubber. I do have a question for you though. Does the stance seem right for the car? I have the GT Pro kit on the car and it just seems too sit higher than most I have noticed on line in pics that have the same kit.

I agree that new shocks would make a difference, but the plan for the time being is to get everything working as it should and keep it original.  I did get new tires today and that made a difference.  A lot less noise, less darty, and a smoother ride.  Cooper was running a rebate on their top of the line all season, Zeon, and so far I'm impressed.  It is a wider tire than the Goodyears they replaced.  They have a nice sidewall past the lip of the rim so it should save the rims and I like the look.  Helps fill out the rear wheel wells some.

Took both birds to supper tonight as the weather is getting a little better.

It would be nice this weekend to be able to wash and wax both of them.

I'm not sure if it will pass SMOG, but you should be able to tap the tank or sending unit area for a brass pipe nipple, and run a vacuum line to the OEM EVAP sensor.  You'll have to run a non-vented gas gap as well.
