But when you put all all those configurations on one spec line it allows you to mix and match.

Does not.

Update/backdate defines "assemblies" in such a way that, while there will be some potential for mix-and-match, we can't completely cherry pick what we do. For example, we've got to use the entire short block as an assembly. I can't put the OBDII-spec head on my OBDI-spec block. In the Volvo example, the entire block/head assembly has got to stay in one piece. If the later FI "assembly" will bolt to that head, OK. If not, too bad.

(Taking your scenario as a given, for illustrative purposes.)
