I really did not experience anything out of the ordinary, no milky oil, no loss of power, could not see any bubbles in radiator, I had to put about a cup off coolant in from time to time, I thought that was just because of it bubbling over when I shut it off. Also when I did the head, took the 39 head that had been cut, and replaced with a 37 head. The 36 head had been cut so you would have to double washer the spark plugs. Think the 37 head has bigger coolant passages, it has smaller spark plugs, it think was really common to see those head swapped, you have a 37 so it should not be an issue
Good luck with her

Joe thanks for info. on Maradyne cooling fans. Since it is 4" deep I assume you had to install it as a pusher since there is only an inch clearance between the radiator and fan blade. How did you convert it from a puller to a pusher - turn blades around or reverse the wiring? Were you able to install the fan between the radiator and grille by accessing through the bottom or did you have to take the grille out?
