Quote: This list will always come down to application and cost. Comparing the low line budget heads to B1MC or the big Indy and Predator stuff is nuts. I think the original poster might find better info if he listed what application he is searching for and in lieu of just raw flow data, perhaps HP and Torque numbers and RPM potential might be more useful in comparing heads. What makes something a race head or a street head? I have built hemis with 500 plus cfm for the street and iron oem heads that ran in the 9s. The line between the two is impossible to define. Just my 2cents but knowing what you are trying to achieve is paramount in navigating the best path to get there. todd
Agreed, we need some info on what type of build he wants to do.
I suggested the B1 MC and PSO as replacement for someone considering FBS heads, which would be a serious wedge build with 4.80 block.
