You didn't say for an LS3. Please be specific when asking for part numbers. This is the whole kit which includes: valley cover, gasket, (8) O-rings, PCV baffle with screw.

And why else would it be posted in the "GEN IV" forum?

That actually appears to be the correct number. After googling it, I found it listed on Thunder's site and an older post here (that I somehow missed).

Thanks!

Found this

FEL-PRO Part # MS96871
Lifter valley cover set; For use when servicing Displacement-On-Demand solenoids

Has anyone used this? Is this the perimeter gasket + O rings in one box? Rock Auto sells this for $60

You don't want this one unless you have dod.

The $32 one from gmpd that thunder racing has is for a non dod cover.

If the engine is not together drill and tap the towers for 1/8" pipe plugs and don't use the o-rings. Gaskets can leak plugs will not.

The Felpro valve cover gaskets are JUNK. Get the black GM ones they don't expand with heat.
