I believe in either this month or last months Mopar Muscle they did a 451 build and use the ProMax heads. I dont remember all the details but I think they flowed around 340 on the intakes ? I know the eng made very good hp (like 675 I think) and torque. I will try to look it up when I get a chance. Ron
