From what I understand the 2v C heads are better for the street. The 4v flow to much air unless your rev'ing 7000 plus range. The 600 carb is the right size, the rest I don't know. Go to Comp Cam's site, get their cam spec sheet, file out as much as you can and call them, they will not answer an email. Let them help you pick a cam. You can call Lunati and compair the too. Best of luck. There are a few "C" on this form so there is some real help out there.
