Yes, the bars bend forward, significantly and a very slight drop..
I have used a tall up angled stem with a fairly short extension .
Consider level with the saddle a starting point for height..
though you may think better of your drop bars
if they were higher and nearer, as well .

My Bike with the mustache bars on it , has a threaded fork.
the stem is an 8 Nitto Dirt drop
off a MB1 take off from the 80's
the 8 is measured up at a 45 degree angle, following the stem Rise,
so its even shorter horizontally than the numbers suggest.
