There are a dew possible causes for this MAF code on your Buick.

If replacing the MAF sensor did not fix it, you need to look closely at the wires at the sensor connector. They may has gotten stretched. If so, the copper wire inside the colored insulation may be broken causing an open circuit. Pull on each wire as it comes out of the sensor connector. If one stretches, it needs to be repaired.

Another possible cause is that during replacement of the head gasket, you may a problem with the PCV valve. There are two O' rings on the PCV valve. If one is missing or broken, that will cause this problem. I have seen this several times.
