From what you've posted, I can tell you don't have much experience building engines. Comp Xtreme Energy cams are going to be on the edge of being streetable. That's going to make it a challenge to tune, and its not going to idle well or make low-end torque. Also, this engine got new pistons and an overbore, not just a cylinder hone, since it says it's 0.040" overbored.
You'll do better with this question in the engine performance section.
Also, you need to state what you want to do with the car. Race? Street/strip? Daily driver/weekend cruiser?
