If you search through the recent threads in this forum, you will find several threads basically asking the same question.

If you are stock, then No, you have to (at a very minimum) install LT4 springs. If you go with a larger cam or step up to 1.7 rr's, you need to upgrade the springs further still.

To phrase in different words: What you will be doing is increasing the lift of the valves (and hence the springs) by increasing the ratio from 1:5 to 1:6. Our springs were not designed for the increased lift, hence they will need to be upgraded to springs that are designed for the higher lift.
