You can make 100 HP easily with the stock displacement. Carbs, cam, and compression will take you over. A little head work and a good exhaust will put you well and truly over.

Don't go over 96mm on stock cylinders (the 93s from the 1.8 or the 94s from the 2.0 only, please!) or the walls get rather thin.

A 2056cc (96mm bore, stock 71mm stroke) can pretty easily make 125 HP with the right cam and compression. And yes, carbs to deal with the cam. Or aftermarket EFI.
