spiralnumbershould do. Currently it is set tospiralnumber=20and you can tryspiralnumber=28. (I cannot compile documents with these fonts.) – Apr 26 '20 at 21:57\textheight. Most users will be fine with your fonts, I am just using a very old editor that only works with ASCII characters. I am too much used to that editor to switch. So you can try to replace\Valor*\textheightby0.95*\Valor*\paperheight(or with0.95replaced by another value<1). – Apr 26 '20 at 22:12
