Quote: You had a couple of options for B1 heads. B1BS and B1 originals. I wonder how well a BS head works when done all out?
IMO, the BS head is no better than a comparably ported RPM head. I have a nice set that flow very comparable to a CNC'd RPM head. The exhaust on the BS head does flow better than a RPM though. But, I do believe the BS head has a larger intake port volume than the RPM. Chamber design is superior with the BS also.
With that said, I see no real reason to buy a BS head, when compared to a RPM. They take special rockers, exhaust port is raised, on and on. Id go -1s/SRs at that point, depending on intended combination.
