Usually a tall order, but for you, only $19.95.  :)

This was pretty much my thinking when I got the 260's.  I figured that
the 2L would make up for any loss of low end, like you.  I hear people
really like the Euro intake cam, it probably has the best bang for the
buck as far as 16v cams go.

People say good things about them, but without some Cam Doctoring or
very expensive back-2-back dyno runs between them and a set of Schrick
260's, I wouldn't trust them at their word.

Once again, the best bang for the $$ would probably be the TT 2.25 stainless
with an Ultraflow.  A header would net you more HP at some rpms, but would
probably be less reliable.  Some people on this list have been running
16v headers for quite some time, so apparently then can last a while.

I think Ben Beacock might have gotten ANSA to make some of these, but
that's just an unsubstainiated rumor.

Sizeable jump?  Not really, 5-7hp in all likelihood.

16v tuning is an expensive past time, if you're serious about making it
fast, be perpared to fork out the big dollars.  Hidden 8v horsepower
is easy to find (throttle body, downpipe, exhaust, increased compression,
etc.) while the 16v is fairly well optimized in stock form.
