<< By the time that all this has been done, would it not have been easier
 to form a mold from high density foam and polysterine, and cast an
 aluminium manifold?  The equipment needed to do this would not be that
 specialised, as we used to make casts at school when I was 14 years old.

The stuff you were casting when you were 14 wasn't hollow.  Don't forget that
a mold for casting something like a manifold requires both inner male plugs
and outer female molds.  To do that, you need a pattern that is a facsimile of
the final part, ie a fiberglass mockup.
