Have to admit not to well versed on the Harley Engine. Is there certain heads for the balanced motor versus the other. I see screaming eagle heads and other brands can you run any of these or what?? Thanks for your info
The main difference between the A motor and the B motor is in the crank case. Everything above the crankcase is the same.
Right now I am running the SE heads on my B motor.
