Manifold Fit
If not, just remove the alignment pins and grind off a little on the diameter and hieght....reinstall the pins and try again...
There are 2 black plastic clips that are taped to the knock sensor wires (under the manifold). Make sure you remove them prior to installing the LS6 manifold. The manifold sets so low that if the clips are not removed, they will keep the manifold from sealing properly against the heads.
Also, dont forget to hook up the small vacumm line that goes between the HVAC system and the rear of the manifold. Its right next to the large brake booster vacumm line.
