I would call Paul and see what he has laying around that could be put together as a package with everything machined then you assemble it yourself.
As mentioned, 701 with at least cleanup porting, B pipe, and increased compression will do take care of most people's needs for quite a while. The next step after that is a 760 from Paul, then a Lamey.
