572 RB Street motor advice?

Depending on your weight and ET goal, and if starting fresh, I would go B1 heads. Or if your looking for the cheaper option, Indy Big EZ325 heads.....The B1's will out run just about anything out there. I run EZ1 heads in my 2650lb car, and it runs 6.12 in the 1/8th...with a 400/512
