3rd party long-distance head porter

There's a member on another Mopar forum I belong to (allpar.com) who is willing to port my #302 318 heads for a modest fee, although he lives over 1,000 miles away in California. I do trust the guy as he seems to be very intelligent and has TONS of experience porting heads, but I would like some recommendations on ways to set up a system that will make sure I get my heads back and he doesn't swindle me in any way. I've had some very long discussions with him on all sorts of technical stuff and he knows way more than I do, so it's not that I don't trust him, it's just a long ways I'd have to ship those heads to someone I've never met in person.
