you may find that a standard "66mm" gasket will work anyway. They tend to be produced slightly larger to allow for rebores IMO.

cheers for the link but just bumping that first question though,

is there any problem with running 70mm head gaskets on a 66mm bore?

Like a nice big gap for heat to build up and problems trying to squish it.
