I'm with Steve, it isn't worth the gamble. I've heard of a few heads from him that weren't too terrible, but some that were total cr@p. I've never heard anyone say theirs was great, or totally ready-to-go out of the box. Do ya feel lucky?

You think the re-built 5 speed's he sells would give me any trouble? As I was eyeing that for a purchase soon to upgrade from my 4 speed.

Same story as the cylinder heads. If it doesn't come in a factory sealed package, I wouldn't chance it.
