If it were me and I was running the stock cam and 1.6 rockers I would invest in a set of lt4 valve springs that can be had for very cheap and that way you will have more room in terms of lift. Of course I have seen many run the stock springs with 1.6 rockers so it can be done but to reduce the risk of coil bind I would personally upgrade the springs.
