If your csc 1.9 rockers would be a good choice for you,you ask if you can use rockers with a cam well yes and no a GT1 cam you could go with 1.7 rockers for maximum lift ,I do'nt think you understand the concept of lift but in short a cam will increase lift and duration over stock wereas hi-ratio rockers eg:1.9 increase lift but have lttle effect on duration ,and another tidbit the 1.95 rockers do'nt actually show any gain over the 1.9's .Chico(pops)
