Default Does the LS3 use rear steam vent bockoffs too

Does the 2008 LS3 engine use the rear pipe blockoff part 313 in the diagram

Mine looks like its got a rivet inside the hole.

Later LS engines went to the plug in the hole ralther than the bolt on cap deal. Now the heads are left and righ hand.
The bare castings and assemblies don't have the plugs so people will still need to procure a set if they buy heads.

Production engines have the plugs.

Is there really any benefit to plugging them? I'm currently running the LS1 Cross-over Tube, it vents all 4.

I'd guess not if the factory plugged them. Two more possible sources of leaks eliminated.
