Might cost you a few specialty tools, but it's a learning experience. Although I can't do my own head & block machining, I do all the assembly now. Only way that I'll know how it went together, especially after an experience or two where "professional" engine builders really let me down.
Hell yes to the learning experience, agreed...
I also believe in doing this yourself wherever possible.
Gearheads are pretty diverse, myself I'd not push anyone in that kind of direction unless they were curious about it and had the desire.
