Is the '90 oil filter head/oil cooler setup full flow to the cooler or is just a portion of the oil pump output channeled through the cooler? And I seem to remember reference to a thermostat that may control this?

Exactly! Its full flow when the oil temperature is high, closed at low temperatures, and somewhere in between full open or closed when the oil temperature is just right.
