This is a new question but same theme. Being that i'm building a new motor. It will be TBI. I'm putting a Holley 670 CFM throttle body and a holley pro-jection manifold. I'll probly put roller rockers as well. My question is...since my motor will be TBI, do i need to stay with TBI Heads(like the one that came stock, and just have them rebuild and ported) or will any heads work fine? Heads are VERY expensive so i want to go the best route posible. Thanks, -regards brian.
