Hey guys, I'm still pondering the possibility of moving up to a better set of heads and intake in the future vs. going the vortech blower route. I currently have a Crane 2031 cam with the stock cobra heads and intake with no port work. Is there a brand of heads that will work better with my cam than others? Will I be able to reuse my cobra 1.7 rockers with a different set of heads or will I have to change? Thanks
