Quote: My list would be Predator....B-1 TS....B-1 PSO.......B1-MC.......B-1.......600-13......572-13......440-1 and then anything else. Might be some debate on the original B-1 vs the 600-13. Also a stretch to call a 440-1 a "race" head as it is common on street cars. I myself would pretty much consider anything less than a 440-1 a street head or street/strip head at best. Just depends on your performance goals and intended use. Just because you have an Edelbrock head on your "race" car, doesn't mean it was designed to be a "race" head.
Likely the LEAST user friendly head of the group is the B-1 TS, as there just are not commonly available parts to make it work correctly. Needs a custom intake and really needs the lifters moved in the block to be optomized

What about the B1 T/S 4.84 heads.. I remember you saying you have a set stashed away, and since the Predators are only 4.80 I would think that puts the B1 T/S on top..
