before replacing the acuators, i would check the chains. they are very common for slacking off and changing timing. the pcm cannot compensate and throws those codes.

My main concern that I need answered is: Should the car run correctly with the Saturn heads and actuators installed? The engine I installed has 37,000 miles on it. Assuming that the timing chain is okay and the current actuators that are installed is okay, what would be your suggestion as to where to go from here. Should I replace the actuators with Cadillac ones and do you think that this might correct the problem?

Engine blocka and head could be similar but if sensors and actuators are different, you should always use the ones on vehicle, not from a donor.

Were these problems present when the engine was replaced 37 k miles ago? If not, I would agree with Roy's sugestion of checking the chains.
