Help with my first engine build (5.9 Magnum)

1999 DODGE RAM 2500 COMP Cams 20-746-9 COMP Cams Xtreme Energy Camshafts | Summit Racing

This is the cam I bought originally, its a little better than stock, but nothing crazy (from what I understand). The iron heads I have are ported some, will that help my situation?

Thanks for the information! This is my first time building a motor with performance parts...
