1.  I don't see how having unburned fuel exit the exhaust is a problem
per se in a B'ville vehicle.
2.  The further upstream the injection occurs, the more chance for the
fuel to evaporate and mix, but also the more air will be displaced by
that evaporated fuel.  I'd go for max air into the engine, and run the
injectors as close to the valve as possible and richen as required.  Or
go one better--direct injection into the combustion chamber a la a few
current oem's.

opinion worth what you paid for it
