bare bones, keeping it simple, getting back the the VW roots....

A goal of 125hp should make for a lively car. Figure a zero to sixty mph in the mid sixes, and a 1/4-mile of 14-15 secs.
A nice 87 or 88 bore engine, with a pair of small IDFs or even Solex 40PII's, stock valved dual port heads with smoothed and softened port contours, increased cam timing (think 120 Engle), and a nice tuned header, the ubiquitous 009 or 010, and a step up in compression.
Great thread.. Making me reminisce about my younger days of adding parts as the money came.
But,
Um,
a 1641 or 1679 with a fly-cut, home port job and a W120 isn't going to be making 125hp.
More like 75.. :P
How these kinds of motors come about in my world is the "heater box motor".
Once you're running stock heater boxes, big valves and stroker cranks go out the window.
All kinds of things become just a waste..
Building a motor around stock heater boxes becomes a fun challenge.
Gives me a chance to use the old German parts we have around.
But,
It's hard to go back,
Once you get used to a big built motor.
Find myself with my foot through the boards trying to talk it into giving more.
"come on Betsy, give me some more here, sweetheart, I need around this truck"..
:D

A 120 cam needs a cc of at least 1835

My 1776cc disagrees with you ;D

;D Lot's of options to work with heater boxes these days. You have the "cheap" "big" heater boxes which are 35mm, should be enough for a "hot 1600" with 100HP and CSP even have bigger different tubing size heater boxes to work with their exhaust range if you really want to go with a stroker crank and 44 valves.
But, I follow you in some sort of way: it's gonna be hard to push a 1600 with a flycut and some home ported heads to a healthy 125HP. But it's certainly doable. What's the trick?
