I'm in the middle of doing this job right now too. It's not too hard, you've just got to take your time and pay attention to what you're removing. I have it kind of easy since I can always just go look at the engine of my other wagon to compare stuff.

The cracks should be very obvious, no special anything needed.

A replacement head, especially a #22 is big $$. Search for a good deal. It will take some time I imagine.

Good luck.
