Why can't you just cut the injector bosses out in one piece, rotate them 180
degrees and reglass it manifold?  The fuel rail would just have to be
rotated 180 also and that would make the change pretty simple.  Not easy,
simple!

If it turns out to be ugly, you could always paint it some other color than
red!  :>)

The alignment is really good, actually.  I've attached a picture of the
completed manifold.  Those shiny spots right
above the injectors are the oil injector bosses.

Looking at this picture has me thinking of a different
modification...turning the fuel rail 90*, and drilling the
upright part of the support.  That would direct the injectors into the outer
runners at about a 30* angle.

OTOH, I do have one of those self-contained HVLP sprayers that could give a
me a good supply of air into the chamber.
