Advice removing heads from 360

Cap clearance looks ok. Only has an electric fan. One of the headers is disconnected at the Y, will do the other before using the jack. This weekend I'll be getting to the driver's side motor mount. It appears to be larger than any socket I own, so I'll add it to the parts store list.

Is it mixing oil and water? Is it smoking out the exhaust?

What do you know about that electric fan? How many CFM does the fan pull?
