I personally wouldn't recommend a 1.6 ratio on a stock motor. For one thing, the benefit with a stock head and cam is minimal. The extra valve lift won't counter the poor flow and other problems of a stock head. For another, stock valve springs aren't meant to handle the increased lift. Wait till you can afford some new heads or rework the ones you have before using 1.6 rockers IMHO. BTW: A friend of mine had his 87 TPI heads reworked for about 400. The intake and exhaust were enlarged (2.02 and 1.94 I think), the intake ports were gasket matched and bowl blended, the spring pockets were machined, press in studs installed along with heavier valve springs. Runs quite nice.
