i think an online illustrated parts manual for an LS1 might be helpful here so i can see them.

There is one on the rear of each head. You still use a crossover tube on the front.

Nothing to them The rear is just 2 little blocks that plug the hole and the front one is the same plugs with a tube welded in.

Look carefully ubove the timing cover see the tube that goes from one head to another that is the cross over http://mycarpics.shutterfly.com/198 If you can see them the little blocks that bolt in the head is what you get for the back. Also look to the left of the black plastis pole (oil pressure sensor) you'll see the plug for the rear of the heads.http://mycarpics.shutterfly.com/202
