Ken,
Did you alter the oil cooler bypass? The stock oil cooler has a bypass that prevents oil from circulating through it when the oil temp is below 140F degrees.
This helps to warm the oil faster on cold days.

Comments welcome,

Why is the oil exchanger out of the question? I
don't see how it could be any more dangerous than a muff.
My plan is to duct either a radiator or the oil
cooler so that I pick up cabin air both in front and behind the heat
exchanger. The cool air pickup in front of the heat exchanger will
run through an icebox, and then both ducts will run into a cabin
controlled 'mixer' to give the maximum in pilot/passenger comfort.

A problem with oil is that I have had problems
with keeping the oil warm enough in cold weather where the water thermostat seems to be more stable.
In cold weather my oil will drop to 120 degrees or less where the water will hold at 180.
