The cam specs that you are using would help.

Current spring pressures? Recommended spring pressures?

Is it even on the 2.9L in your signature?

As long as the cam is not much bigger than stock the stock springs should be fine. To much spring can be just as bad as not enough.

A lot has to do with what your trying to use the motor for. If you want high rpm's then you need stonger springs to eliminate valve float. If you want a daily driver and the numbers are close you shouldn't have a problem. How agressive is the cam? How close are the valve springs?
