This is from personal experience. When you get the head off, check the depth of the valve heads compared to the deck of the head. If they are not within spec, get the seats replaced and so they are back into spec. This will improve cold starting. The gasket mating surfaces of the block and head should be flat. I worked on a 460 once that was notorious for leaking water to the outside and I found a depression about the size of a nickel in the deck of the block. I decided to try JB weld (it had just come out) to fill it and it solved the problem.

Depending on how it was starting and running before, you might want to consider having the injectors and injector pump checked. Were you loosing any water? If so, in addition to the head you will want to check the sleeves, etc. Oil consumption and blow-by should be considered as if either is excessive; you might want to do a complete rebuild if you use the tractor enough.

Just some thoughts. I bought one about 22 years ago that wouldn’t start below +40 F without an M and a log chain in front. After I rebuilt and fixed valve seats, valve guides, put in new sleeves & pistons, worked injectors and pump, etc. The engine was back to spec and would start to at least -10 F without being plugged in. Found out the hard way one day when the block heater failed and it still started! Gotta love them when they do that! :>)
