If you go with a 1g head, you should swap to a 1g intake manifold. If you swap to a 1g intake manifold, you have to mess with the wiring a bit anyhow. You have to extend the wires for the coil and the power transistor. In my case, the car had a bad CAS so it was an easy decision to swap to a 1g cas. Other than extending the wires above, I did not do anything else regarding "hacking" the wiring. I made a snap in connector to adapt the 1g cas to the 2 sensors.
