Gran Prix GTP 1.9 Ratio Rockers

ZZ Performance offered a 1.9 ratio rocker for the 3.8 sc V-6 that comes in a Grand Prix GTP 98. They made these rockers themselves from old rockers that are sent in as a core, from the information i was given. I know nothing about rockers, can a 1.6 be made into a 1.9 ratio? And can a 3.8 with bolt-on mods handle a 1.9 ratio without any internal engine work. Im just wondering i have a freind that purchased these claims 15-20 at the wheel, but honestly i dont see it.
