diameter and embedment depth but it is not apparent what rational is
being used. It allows design based half a dozen methods but it will only
specify proprietary Hilti post-installed anchors. These may have their
own spacing requirements.

See ACI 318-05, Appendix D, Section D.8. Good practice would still
dictate consideration of concrete consolidation - rebar spacing
limitations would provide reasonable minimum spacings.

Not that I am aware of. It would just be rebar spacing type
requirements (i.e. requirements to insure concrete around the anchor rod
and nut/head).
The possible exception is something in Appendix D. I have not really
"played" too much with Appendix D, I am don't know if there is any thing
in there. If I get a chance, maybe I will take a looksie.

Is there a minimum spacing for anchor bolts besides what's required to
allow
concrete to flow around the head and body of the bolt per ACI?
TIA
