I need a little bit of help trying to find a set of heads, i have a '70 small block bored 40 over at about 12:1 compression. I need to know how many CFM's it will take to get a 3200lb down the quarter in about 11sec. im running 12:72 now with a 4:11 gear in the rear with a set of 202 ported to the max double hump heads, with a edelbrock intake and a holley 750 double pumper, i am looking to knock at least a second of my E.T with a set of heads i was looking at the Victor Jr's. ANY help would be appreciated.
